An interim agreement between the United States and Iran, set to be officially signed in Switzerland, is intended to create a two-month window to negotiate the core dispute over Iran’s nuclear program. The deal is framed as a step toward preventing Iran from acquiring a nuclear weapon, a concern cited by U.S. President Donald Trump. While relatively few details are publicly available, the interim accord broadly includes steps related to reopening the Strait of Hormuz to global oil shipments, U.S. and regional officials say, and providing economic incentives to Iran tied to benchmarks. It also provides for a 60-day period for negotiations on ending Iran’s nuclear program.

Multiple accounts report widespread skepticism across U.S. political and pro-Israel circles, including lawmakers in both parties and Israel itself, questioning whether the arrangement is realistic and whether it will produce meaningful progress on the nuclear issue—particularly Iran’s enrichment activities. Trump administration officials argue the structure links benefits to Iranian actions, with the Vice President emphasizing a phased approach. Critics point to the shorter timeline compared with the 2015 JCPOA, which took more than 18 months and relied on extensive technical work and international involvement, and to uncertainty over whether other regional issues will be addressed alongside nuclear talks.
