[Ed. – The stated time of reimposition was 8:00 PM Eastern on Saturday the 19th. So it’s done. The impact on other nations will be felt through U.S. enforcement; i.e., at the president’s discretion, we will sanctions their activities (e.g., banking, trade) as they relate to facilitating the violation of sanctions by Iran. This is a major move opposed by almost all of the UN Security Council — the very nations we’ll have to sanction if they continue to defy us. It’s a good thing we know how to walk and chew gum at the same time.]
U.S. President Donald Trump’s administration says that on Saturday (2000 EDT Sunday) all United Nations sanctions on Iran have to be restored and a conventional arms embargo on the country will no longer expire in mid-October.
A return of U.N. sanctions, a so-called snapback, would require Iran to suspend all nuclear enrichment-related and reprocessing activities, including research and development, and ban imports of anything that could contribute to those activities or to development of nuclear weapon delivery systems.
It would reimpose the arms embargo, ban Iran from developing ballistic missiles capable of delivering nuclear weapons and bring back targeted sanctions on dozens of individuals and entities. Countries also would be urged to inspect shipments to and from Iran and authorized to seize any banned cargo.
