A key recent exchange:
Q But you definitively believe Iran wants to build a nuclear weapon?
THE PRESIDENT: I think so long until they suspend and/or make it clear that they that their statements aren’t real, yeah, I believe they want to have the capacity, the knowledge, in order to make a nuclear weapon. […]
So I’ve told people that if you’re interested in avoiding World War III, it seems like you ought to be interested in preventing them from have the knowledge necessary to make a nuclear weapon. I take the threat of Iran with a nuclear weapon very seriously.
They "want to have the capacity, the knowledge, in order to make." Makes more sense now, doesn't it?
