President Trump wants Assad out and promised to wipeout ISIS, whom we are fighting against right now. Learn about that which you post about.
I hope that Trump is smart enough to know that if you reach for 2 separate objectives you won't reach either. He's very close to taking ISIS off the board. Finish the job. Then worry about Assad. After all the Russians have Assad's back. It's going to take something other than direct US military action to eliminate him.
