(NBC)- President Donald Trump says negotiations between the United States and Iran to end the war are set to resume Monday, just days after he threatened major new military strikes against Iran. Speaking Sunday, Trump said the U.S. was prepared to launch what he described as its largest military strikes since World War II. “The back channel diplomacy worked really hard to convince President Trump to give a chance to diplomacy again,” Al-Etaibi said. Trump, however, insisted the U.S. remains prepared to use military force if necessary but said he would rather reach a diplomatic agreement.
