Marco Rubio

In the Sept. 16 debate, the first-term Republican senator from Florida did not say precisely what he would do about the JCPOA as president, but expressed doubt that Iran would abide by the agreement.

“Anyone who is paying attention to what [Supreme Leader Ayatollah Ali] Khamenei says knows that they will not comply,” Rubio said. “In the middle of negotiating this treaty, Khamenei led the assembled masses in chanting ‘Death to America.’ … We need a commander in chief who will stand up and protect this country. And I’ll tell you, I can’t wait to stand on that debate stage with Hillary Clinton and to make abundantly clear if you vote for Hillary, you are voting for the Ayatollah Khamenei to possess a nuclear weapon and if you elect me as president, under no circumstances will a theocratic ayatollah who chants ‘Death to America’ ever be allowed to acquire a nuclear weapon.”
