Former Sen. Rick Santorum invoked a nuclear deal signed with North Korea in the 1990s as a reason why one with Iran will not work out.

Shortly after a framework agreement was put in place with North Korea in 1994, the country developed a nuclear weapon — and this is what will likely happen with Iran, the one-time Republican presidential hopeful said on CBS' "Face the Nation" Sunday. However, with Iran, it's different, he explained.

"It's [the deal] going to give them the opportunity to have a financial resurgence ... to move forward, and to do even more dangerous things," he said.

Unlike North Korea — "whose objective is to survive," according to Santorum — Iran will work to get a nuclear weapon and use it for no good.

"Iran is an expansionist Islamic theocracy whose objective is not to survive, but to spread radical Islam throughout the world," he said. Iran doesn't care about survival, it cares about "bringing about the end of times so it can conquer the world.

"This is a dangerous, dangerous country to be messing with nuclear weapons," Santorum said.

Santorum's solution? "Ramp up those sanctions," he said, "and drawing clear lines in the sand."
