Biden Fails to Restore Iran Nuclear Deal After Trump Withdrawal

After four years of negotiations, the Biden administration failed to revive the 2015 Joint Comprehensive Plan of Action (JCPOA) that Trump abandoned in 2018. Iran accelerated uranium enrichment to 60 percent purity — approaching weapons-grade levels — while indirect talks in Vienna and Doha collapsed repeatedly. By 2024, Iran had accumulated enough enriched uranium for multiple nuclear devices, marking the complete failure of the Biden diplomatic strategy.
