President Trump announced Tuesday that the U.S. will withdraw from the Iran deal, which suspends punishing economic sanctions on Iran in exchange for Tehran's commitment to curbing its nuclear program. "In theory, the so-called Iran deal was supposed to protect the U.S. and our allies from the lunacy of an Iranian nuclear bomb," Trump said, but "in fact, the deal allowed Iran to continue enriching uranium." French President Emmanuel Macron said France, Germany, and the U.K. — other signatories of the deal — regret the U.S.'s decision to withdraw, warning that "the nuclear non-proliferation regime is at stake." CNN's Christiane Amanpour called Trump's decision "possibly the greatest deliberate act of self-harm and self-sabotage in geo-strategic politics in the modern era."
