The current problem is the likely US military intervention. The only immediate solution is demanding US politicians stop the insanity.

Pete, regarding the problem of oppressive, murderous regimes (of varying degrees, Assad moving to one of the worst, but not the top), I disagree that there's nothing outside agents can possibly do. There are many things; killing just is not one of them. I would offer citizenship and all its rights from a better government, to anyone who wants it.
