To his credit, Rubio, like Cruz, was a staunch opponent of President Obama’s agreement to provide over $100 billion to the world’s leading state sponsor of terrorism while rendering that regime a threshold nuclear power. Yet, in a manner reminiscent of the Gang of Eight, senior Beltway Republicans joined the Obama Left in crafting the so-called Corker-Cardin legislation, a bill that would prevent Congress from rejecting the deal.

So Rubio, like Cruz, proposed amendments in an effort to blow up the deal. Rubio, for example, proposed that any agreement require Iran’s leaders to accept Israel’s right to exist. Rubio well knew this poison pill had no chance of being adopted. But he was not trying to improve the Iran deal. Rubio was, as Time magazine observed, trying to kill the Iran deal.

Now, using the logic of Rubio’s “amnesty” attack on Cruz, one could argue that, if the deal satisfied the condition that Iran acknowledge the Jewish state’s legitimate existence, Rubio would support it — despite the agreement’s material support to terrorism and facilitation of Tehran’s nuclear and ballistic-missile programs. That, however, would be a smear.
