Iranian President Hassan Rouhani said on Tuesday US President Donald Trump cannot cause its nuclear deal with six major powers to collapse, Reuters reports. “The nuclear deal will not collapse… Those who hope that Trump will cause its collapse, are wrong,” Rouhani said in a speech broadcast live on state TV. In October, Trump declined to certify that Iran was complying with the nuclear agreement Tehran had reached with world powers in 2015. Iran says it will stick to the accord as long as the other signatories respect it, but will “shred” the deal if Washington pulls out.
