Efforts by European nations to find ways for businesses to work around United States sanctions on Iran are unlikely to succeed. Diplomats and experts say those efforts are likely to face difficulties after the Iranian government’s decision to violate its 2015 nuclear deal with world powers. The International Atomic Energy Agency reported on Monday that Iran breached the agreed limit on its supply of low-enriched uranium. The experts say the financial mechanism, developed by European nations that signed the deal, will not provide Iran with enough to make up for the loss of trade and oil sales. U.S. President Donald Trump withdrew the United States from the nuclear deal last year. He said that the deal did little to prevent Iran from making a nuclear weapon. He also noted that the country continued to support conflicts in the Middle East.
