While Trump did not pull the United States out of the agreement, aimed at preventing Iran from developing a nuclear bomb, he gave the US Congress 60 days to decide whether to reimpose economic sanctions on Tehran that were lifted under the pact.That would increase tension with Iran as well as put Washington at odds with other signatories of the accord such as Britain, France, Germany, Russia, China and the European Union.
