The difference between Syria today and Syria without Assad would be the same as Iraq without Saddam or Lybia without Ghadaffi. It takes a real special sort of person to claim the country wouldn't devolve into even more ethnic cleansing than has already been caused by our own hands. You didn't follow Syria, you don't know shit about the situation, about the context, about the war that has been going for longer than WW2 did. And you most def don't know shit or care about the tribal/ethnic divisions that were exploited to create this situation in the first place, or even the barest inkling of how the situation would play out in the void left by Assad.
Tell me, if you had the option to go back in time and decide whether the West should depose Ghadaffi with their retarded Muh bootiful Arab Spring democracy propaganda/simultaneously funding insanely extremist jihadist rebels, the exact same MO as was attempted in Syria, would you still do it? With your absolutely fucktarded perspective of ignoring both the past and future consequences and acting entirely on whatever stupid fucking slop you're forcefed? And then you have the nerve to pretend your point of view is the rational and logical one. Again, fucking kill yourself. You're too dumb to live and your death could only fractionally improve humanity as a whole.
