Mexico deployed 10,000 National Guard troops to the border after Trump's tariff threats. But border encounters had already dropped 60% in the six months before his inauguration. Who gets credit?

Trump previously said "Mexico does what we tell them to do" despite Sheinbaum's cooperation on border security and cartel extraditions. How does this language affect the US-Mexico relationship?

At the joint press availability on September 3, 2025 in Mexico City, Foreign Affairs Secretary Juan Ramón de la Fuente said, “models of cooperation, of collaboration can be built that work, that give results” (Press Democrat, Sep. 3, 2025). Yet U.S. Customs and Border Protection recorded 2.1 million migrant encounters in FY 2024, only a 14% drop from FY 2023, and CBP along with HSI seized nearly 460,000 lbs of fentanyl from FY 2021–FY 2024 (GAO-25-107667). What “results” is he referencing?
