Didn't we learn anything from the "deal" with North Korea?

This story, 'Kerry and EU would offer Iran a nuclear deal', leads me to believe that the Democrats have fogotten all about the failure of the deal brokered with North Korea.

"If we are engaging with Iranians in an effort to reach this great bargain and if in fact this is a bluff that they are trying to develop nuclear weapons capability, then we know that our European friends will stand with us," Democratic vice presidential nominee John Edwards said.
