BERLIN, May 6, 2018 (News Wires) – French President Emmanuel Macron said that a decision by US President Donald Trump to withdraw from the Iranian nuclear deal could spark a war. "We would open the Pandora's box. There could be war," Macron told German weekly magazine Der Spiegel. But he added: "I don't think that Donald Trump wants war." Trump is set to decide by May 12 whether to pull out of the Iran deal. Trump has all but decided to withdraw but exactly how he will do so remains unclear, two White House officials and a source familiar with the administration's internal debate said on May 2. Trump could still figure out a way to stay in the deal between the Islamic Republic and six world powers — Britain, China, France, Germany, Russia and the United States. Britain, France and Germany remain committed to the accord but, in an effort to keep Washington in it, want to open talks on Iran's ballistic missile program, its nuclear activities beyond 2025 - when key provisions of the deal expire - and its role in Middle East crises such as Syria and Yemen.
