I would be all for overthrowing Assad and pushing Iran’s influence out of the area, and heck, if they get a pipeline in the bargain, icing on the cake.
The problem is when they chose Al Qaeda and Al Qaeda In Iraq (ISIS) to do the dirty work... and these guys were turned loose to commit genocide against regional Christians for rest and recreation.
Once that happened, it became impossible for ordinary Americans to ever support this war.
Only a guy like Obama and the nimrods at the obamist State Department could screw this up. By picking as his proxies and allies the worst monsters on the planet, he destroyed Syria, he destroyed his own policy. And turned Assad into a hero.
Assad is basically another Saddam Huessein. A terrible guy, but probably best for protecting Christians from Islamsists.
