Much like with Iraq, the US started from their politically-based desired answer, and worked backwards to justify them.
The EU seems to be evaluating the situation based on facts.
The Iran nuclear accord, assailed by President Trump and his revamped retinue of advisers, received a strong endorsement Monday from a bipartisan group of more than 100 national security veterans, who said the United States gains nothing by scrapping it.
The group, including 50 retired military officers and at least four former American ambassadors to Israel, added its voice to a fractious debate over the accord, which Mr. Trump has called “the worst deal” ever.

Iran is adhering to the restrictions imposed on its nuclear program under a 2015 agreement, the United Nations agency charged with monitoring the country's facilities has said in its first report since President Trump refused to certify the Islamic republic's compliance.
The International Atomic Energy Agency (IAEA) said in a confidential report viewed by Reuters and several other news outlets Monday that Iran's stockpiles of enriched uranium have not exceeded the agreed limit of 300 kilograms. It also reported that IAEA inspectors were able to gain access to any sites they tried to visit.
The quarterly report marked the ninth successive time the IAEA has attested that Iran is meeting its commitments since the nuclear deal between Iran and six major powers, including the United States, was implemented early last year.

Days after the US president walked away from a three-year-old deal that mandated rigorous scrutiny of Iranian facilities, senior administration officials said monitoring should continue regardless.
