The question all the reporters asked was "What are you gonna do about the Paris massacre?" Obama evaded gracefully, evaded the followup questions, and managed to spend 45 minutes on live TV saying that he isn't going to do anything on account of the Paris massacre. He still wants to bring in a LOT of Syrian refugees to the US. He isn't going to take any action, military or otherwise against ISIS.
Obama claimed that Syrian refugees would be "vetted" before they are allowed into the US. Hah. Tell me about how you gonna do that. Pick up the phone and call Baghdad? And ask if Mohammed so-and-so is an ISIS terrorist? Who's gonna answer that phone? Assad's flunkies? ISIS, the other rebel groups? And even if they wanted to, can they check public records in a country undergoing a civil war? I don't think so.
Syrian refugees are a gamble. Most of 'em are probably harmless refugees, some of 'em are ISIS, some of 'em are Al Quada, some of 'em are other bad things. And they all look alike.
