Bill Maher: Ok, alright I'm surrounded by my friends. Rick Santorum what are your thoughts on the Iran nuclear deal? I'm guessing you love it because it's Obama?  Whatever he does your good with.

Sen. Rick Santorum: He violated the first principle, you don't negotiate with terrorists and we negotiated with a terrorist organization.

Maher: Well Reagan did.

Santorum: You don't negotiate with terrorists. We didn't negotiate with terrorists.

Maher: Well Reagan did, is that not your boyfriend.

Santorum: We don't negotiate with terrorists.

Maher: Reagan never negotiated with terrorists? He admitted it on the air with Iran-contra, that wasn't negotiating with terrorists?  Reagan not only negotiated with terrorists they also cut and ran. When the bombing happened in Beirut in '83, George Bush, his Vice President went over there and said 'this will not stand or whatever' and then we cut and ran.

Santorum: Reagan was wrong.

Maher: 'Reagan was wrong!' Oh my god.

Santorum:  Look, this was a relatively new threat way back then and you know radical Islam was emergent at this time, he had a whole different fish to fry, he had the Soviet Union he was trying to destroy, his attention was on that.

Maher: So the whole country has to be terrorists?

Santorum: Look it's not who the country is, it's who is running the country and the people running the country are a death cult, they are a group of radical Muslims, Shia Islamists, who are more concerned about the hereafter than they are the here and now.

Rep. Dana Rohrabacher:  Our problem, Bill, with what the policy has been over the years is that while we've been negotiating this rotten treaty, which is gonna give this regime a hundred and fifty billion dollars to spend on terrorism, all this time we have hesitated to help the people of Iran flight this regime.
