Florida Senator Marco Rubio has followed up Senator Tom Cotton's Iran baiting with a warning: the current deal with Iran on its nuclear program will result in war.

Rubio said the current deal will prompt Israel to attack Iran. "I would argue that a bad deal almost guarantees war, because Israel is not going to abide by any deal that they believe puts them and their existence in danger," he told the National Review Institute Ideas Summit.

Rubio, who recently announced a bid for the presidency, said Iran will "exploit any loophole in a deal that it can find" and use the arrangement to attack the West.
