Three key European nations and the United States have moved to censure Iran over its secretive nuclear program, hoping to shore up the credibility of the world’s nuclear watchdog before Donald J. Trump’s return to the White House.

The United States and the three European nations involved — Britain, France and Germany — put forward a resolution on Tuesday condemning Iran for its consistent refusal to answer questions from the International Atomic Energy Agency, the U.N.’s nuclear monitoring organization, about its nuclear enrichment program.

The resolution to censure may be voted on at the agency’s regular meeting of its board of governors in Vienna as soon as Wednesday or Thursday. If the measure passes, it could ultimately lead to retaliatory measures against Iran by the West.

The censure resolution followed the circulation of a report at the agency earlier this week detailing Iran’s expansion of its stockpile of enriched uranium that is close to weapons grade and its consistent efforts to block the IAEA from monitoring its progress.

The countries pushing for the censure are concerned that Iran’s continued recalcitrance presents a significant threat to the Nuclear Nonproliferation Treaty and undermines the credibility of the IAEA itself.
