Saddam was an equally bad actor and we got rid of him and we are so much better off now?  Time to stop meddling in things that we can't predict the outcome of.  Getting rid of Assad leaves the way clear for ISIS and company.  There is no evidence that Gabbard's visit in any way legitimizes his act, any more than BO's cozying up to Raul Castro legitimizes all the bad stuff he and his big bro have done over  the decades.
