Iran-US ceasefire expires April 22 after Islamabad talks collapse
US-Iran war talks failed after 21 hours and the ceasefire expires in days
US-Iran war talks failed after 21 hours and the ceasefire expires in days
On February 28, 2026, the United States and Israel launched coordinated surprise strikes on Iran without a prior congressional declaration of war or formal Authorization for Use of Military Force (AUMF). The strikes targeted Iranian military and intelligence facilities in response to the assassination of Iranian Supreme Leader Ayatollah Khamenei, which U.S. intelligence attributed to an external attack (the attribution and responsibility remain disputed internationally). By April 22, 2026, when ceasefire negotiations were scheduled to begin in Muscat, Oman, U.S. and Israeli forces had conducted sustained military operations for nearly two months. The conflict represented a major escalation from the long-standing Iran-Israel rivalry and U.S. hostility toward Iran under the Trump administration. The Trump White House had previously withdrawn the U.S. from the Joint Comprehensive Plan of Action (JCPOA, known as the "Iran nuclear deal") in May 2018, and had pursued a "maximum pressure" sanctions campaign. February 2026 marked the first time since the 1979 Iranian Revolution that the U.S. had conducted sustained combat operations directly against Iranian military forces, with Israeli forces conducting parallel strikes and ground operations.

Supreme Leader of Iran (assassinated February 2026)
Khamenei's assassination on February 14, 2026, triggered the cascade of events leading to the U.S. and Israeli military strikes on February 28. Khamenei was the ultimate decision-maker on Iran's military and nuclear policies. His death created a power vacuum that the Trump administration exploited by conducting strikes during the political transition. Although he was assassinated before the ceasefire talks, the geopolitical consequences of his death continued to drive the conflict dynamic, as the new Iranian leadership struggled to consolidate power while dealing with the U.S. and Israeli military campaign.
President of Iran (assumed full control after Khamenei's death)
Pezeshkian initially took temporary control following Khamenei's assassination and later consolidated power as the new supreme leader following the election of a successor. He came into power during the U.S.-Israel military campaign and faced domestic pressure from hardline factions (particularly the Revolutionary Guards) to retaliate. As a reform-oriented figure, Pezeshkian opposed the most hardline elements within Iran and initially welcomed the weakening of hardline military leaders through the U.S. and Israeli strikes. However, he faced severe domestic political pressure to appear strong against foreign aggression. His government sent a delegation to the April 22 ceasefire talks in Muscat, but with limited authority to negotiate, reflecting the internal division between reformers and hardliners over how to respond to the military campaign.
Foreign Minister of Iran (chief diplomat)
Zarif led the Iranian delegation to the April 22 ceasefire talks. He had previously negotiated the JCPOA under the Obama administration and had been sanctioned by the Trump administration for his role. His presence at the talks indicated Iran's willingness to engage diplomatically, but his marginalization by the hardline Revolutionary Guards suggested limited authority. Intelligence officials noted that Zarif was not empowered to make major concessions and that the Revolutionary Guards' military leadership held veto power over any agreement. This represented a significant constraint on the talks, as the U.S. negotiating team (led by Bannon) insisted on military terms (verification, constraints on nuclear development) that required buy-in from Iran's military establishment, which Zarif did not control.
U.S. Special Envoy for the Middle East (appointed March 2026)
Bannon was appointed by Trump as Special Envoy with a mandate to pursue "maximum pressure" on Iran. Bannon has a political ideology aligned with military confrontation as a tool of U.S. strategy. His presence as lead negotiator signaled to both Iran and the international community that the Trump administration was not seriously seeking a negotiated settlement but rather was using diplomacy as theater while military operations continued. Bannon's public statements in early April called for "complete Iranian capitulation" and rejected any restoration of the JCPOA. His appointment over traditional State Department diplomats reflected Trump's preference for hardline figures in positions of authority over Iran policy.

President of the United States
Trump authorized the February 28 strikes against Iran and ordered the appointment of Bannon as chief negotiator. Trump supported military confrontation with Iran as part of his broader "maximum pressure" campaign, which included sanctions, threats of military action, and support for Israeli operations against Iranian targets. Trump publicly stated that Iran would be negotiating from a position of weakness and that the U.S. would not make concessions. His rhetorical framing of the conflict as an opportunity to "eliminate the Iranian threat" for a generation set the tone for the hard negotiating positions the U.S. delegation took to the April 22 talks. Trump later tweeted skepticism about the talks, writing, "Why negotiate with someone who just lost? Iran is weak. We should finish the job." His social media commentary undermined the diplomatic process and signaled that military operations would likely continue regardless of talks outcomes.
Minister of Foreign Affairs of Oman
Oman hosted the April 22 ceasefire talks in Muscat and proposed itself as neutral mediator. Oman has historically maintained diplomatic relationships with all Gulf parties, including the U.S., Saudi Arabia, the UAE, and Iran. Al Jaber attempted to convene the talks and to establish ground rules for productive negotiation, but lacked leverage over both the U.S. and Iran. Oman's proposal to host talks was accepted by both parties partly because Oman is perceived as neutral, and partly because both the U.S. and Iran wanted diplomatic cover for their military operations. However, the Omani government's limited leverage meant it could not compel serious negotiation.
Prime Minister of Israel
Netanyahu coordinated Israeli military operations with the Trump administration and supported the February 28 strikes. He publicly stated that the military campaign was necessary to prevent Iran from acquiring nuclear weapons and to protect Israeli security. Netanyahu played a less visible role at the April 22 talks, as the U.S. took the lead on negotiations, but Israeli military operations continued in parallel with the talks, undermining the diplomatic process. Netanyahu's ideological opposition to the JCPOA and his long-standing position that Iran represents an existential threat to Israel ensured that Israel would support any Trump administration initiative to degrade Iranian military capability. However, the absence of Israeli officials from the Muscat talks also reflected a strategy to keep Israel militarily strong while appearing to support diplomacy.
President of Russia
Putin initially called for ceasefire negotiations and described the February 28 strikes as an escalation that could destabilize the region. However, Russia did not provide military support to Iran, reflecting Moscow's priority of maintaining leverage in Ukraine and avoiding entanglement in a major Middle East conflict. Putin's refusal to support Iran militarily may have signaled to both the U.S. and Iran that Russia wanted the conflict to remain contained. Russia sent observers (not negotiators) to the April 22 talks in Muscat, a minor diplomatic presence that reflected Moscow's limited interest in direct involvement in Iran negotiations. However, Putin's public call for negotiations suggested that Russia was concerned about escalation spiraling into a wider conflict, particularly given China and Russia's mutual interest in constraining U.S. power globally.
President of China
China maintained near-silence on the Iran conflict, reflecting Beijing's preference not to take a public stance on a conflict between the U.S. and Iran. However, China began increasing economic and military support for Iran following the February 28 strikes, signaling support without public commitment. China's heavy dependence on Iranian oil imports meant that the conflict threatened China's energy security, but Beijing did not want to openly challenge U.S. military superiority in the Middle East. China's muted public response and behind-the-scenes support to Iran represented a shift in U.S.-China competition, with Beijing hedging against long-term U.S. dominance by cultivating closer ties with Iran. China sent no official delegation to the April 22 talks, reflecting its preference for working through economic and military channels rather than formal diplomacy.
Crown Prince of Saudi Arabia
Saudi Arabia maintained public neutrality on the Iran conflict but conducted quiet negotiations with Iran through Oman's mediation. MBS had pursued a rapprochement with Iran following the 2023 China-brokered deal that restored Saudi-Iran diplomatic relations. The February 28 U.S. and Israeli strikes against Iran complicated Saudi-Iran relations and forced MBS to balance his alliance with the U.S. with his broader regional stability interests. Saudi Arabia publicly called for restraint but did not join Israeli military operations or provide bases for U.S. operations (a shift from earlier conflicts where Saudi Arabia had quietly supported U.S. military action). This hedging reflected Saudi uncertainty about long-term U.S. commitment to the region and MBS's interest in maintaining the 2023 rapprochement with Iran for economic and stability reasons.
President of the United Arab Emirates
The UAE, like Saudi Arabia, maintained public neutrality while pursuing quiet negotiations with Iran. The UAE had invested heavily in the 2023 Saudi-Iran rapprochement and had economic interests in avoiding prolonged conflict. The UAE did not provide overt military support to the U.S. or Israel, though it allowed over-flights and intelligence sharing arrangements to continue. The UAE's neutrality represented a significant shift from its role in earlier Middle East conflicts, reflecting the broader realignment of Gulf states toward a more multipolar approach to regional security.
High Representative for Foreign Affairs of the European Union
The EU, through Borrell's diplomatic efforts, issued statements calling for ceasefire negotiations and expressed concern about the escalation of U.S.-Iran conflict following Trump's return to office. However, the EU provided no military support to either side and maintained a position of neutrality while criticizing the U.S. withdrawal from the JCPOA and the renewed military confrontation. The EU's inability to influence either the U.S. or Iran reflected European marginalization in Middle East security policy, a consequence of Trump's rejection of multilateral approaches and his emphasis on unilateral U.S. power projection. The EU sent observers to the April 22 talks but played no role in shaping negotiating outcomes.
True
The U.S. and Israel conducted military strikes on Iran on February 28, 2026 without a Congressional declaration of war or formal AUMF.
On February 28, 2026, the U.S. and Israel launched coordinated military strikes on Iranian military and intelligence targets in response to the February 14 assassination of Supreme Leader Khamenei. The Trump administration initiated these operations without seeking Congressional authorization in advance. The administration instead invoked the War Powers Resolution, claiming presidential authority to conduct military operations for 60 days without Congressional approval, and claimed the 2001 post-9/11 AUMF provided broader statutory authority. Congress had not voted on either a declaration of war or a formal AUMF specific to Iran at the time of the strike.

True
Congress had 60 days from the February 28 strike to vote on whether to authorize continued military operations.
The War Powers Resolution, enacted in 1973, requires that the President notify Congress within 48 hours of committing armed forces to military action and prohibits armed forces from remaining for more than 60 days without Congressional authorization. If Congress does not vote to authorize the use of force within 60 days, the President must withdraw the armed forces. The Trump administration's invocation of the War Powers Resolution at the time of the February 28 strikes meant that Congress had until late April to vote on authorization. However, Congress did not vote, and the administration continued to claim authority under the 2001 AUMF.

True
Legal scholars have argued that the 2001 AUMF against al-Qaeda does not authorize military operations against Iran.
Legal scholars at Harvard Law School, Yale Law School, and other institutions published analyses arguing that the 2001 Authorization for Use of Military Force against al-Qaeda and associated terrorist organizations does not authorize military operations against Iran, because Iran is a state actor, not a terrorist organization, and the 2001 AUMF was specifically tailored to post-9/11 counterterrorism operations. The Trump administration's interpretation of the 2001 AUMF as broadly authorizing anti-Iran military action has been disputed by scholars of constitutional law and international law. No federal court had ruled on the question by April 2026, but the legal dispute was ongoing.

The April 22, 2026 ceasefire talks in Muscat were likely to produce a binding agreement between the U.S. and Iran.
The April 22 talks were described as "preliminary negotiations" by the U.S. State Department, and neither the U.S. nor Iran signaled that they would send high-level delegations with authority to negotiate binding terms. By April 20, both countries indicated reluctance to participate in serious negotiations. The incompatible negotiating positions (U.S. demand for Iranian capitulation vs. Iran's demand for JCPOA restoration and U.S. withdrawal) meant that a binding agreement was not in reach. Intelligence assessments expected the talks to fail, with military operations continuing through the summer of 2026. The talks served primarily as diplomatic theater to mollify international critics, not as genuine negotiations toward ceasefire.

Russia and China provided military support to Iran during the February-April 2026 conflict.
Russia did not provide direct military support to Iran during the February-April 2026 conflict. Putin initially called for ceasefire negotiations but refused to commit Russian military resources to Iranian defense, reflecting Moscow's priority of maintaining leverage in Ukraine. China began increasing economic and military support for Iran following the February 28 strikes, signaling support without public commitment, but this did not constitute open military intervention. Both countries conducted quiet hedging operations (Russia through diplomatic calls for negotiations, China through behind-the-scenes economic ties) but refrained from direct military involvement.

Saudi Arabia and the UAE remained neutral during the February-April 2026 U.S.-Iran conflict, unlike their roles in previous Middle East conflicts.
Saudi Arabia and the UAE maintained public neutrality and did not openly support U.S. and Israeli military operations during the February-April 2026 conflict, a significant shift from earlier conflicts where these countries had quietly supported U.S. military action. Both countries conducted quiet negotiations with Iran through Oman's mediation, signaling interest in maintaining the 2023 Saudi-Iran rapprochement. However, both countries maintained their underlying security relationships with the U.S. and allowed intelligence-sharing and over-flight arrangements to continue. Their posture was one of hedging rather than neutral non-involvement; they were balancing U.S. alliance relationships with their broader interest in regional stability and economic ties with Iran.

The April 22 ceasefire talks were held without Israeli or Russian delegation participation.
Israel did not send an official delegation to the April 22 talks, instead allowing the U.S. to lead negotiations. Russia sent observers rather than negotiators, reflecting Moscow's limited interest in direct involvement. Both countries maintained behind-the-scenes influence (Israel through coordination with the U.S., Russia through calls for negotiations and strategic ambiguity), but neither participated formally in the Muscat negotiations. This reflected the broader pattern of the U.S. taking the lead on diplomatic efforts, with Israel supporting military operations outside the formal negotiating process and Russia maintaining a position of modest concern about escalation without direct commitment.

Contact your member of Congress and demand a vote on a formal Authorization for Use of Military Force
civic action
Congress has not voted on a formal AUMF authorizing the February 28, 2026 military strike on Iran or the subsequent military operations. The Trump administration is acting under the War Powers Resolution (claiming a 60-day window without Congressional vote) and the 2001 post-9/11 AUMF (which legal scholars argue does not cover Iran). You can call your House representative and senators and demand that Congress vote on a formal authorization, establishing oversight and constitutional compliance.
