The blood of countless thousands in Syria drips from the hands of psychopathic warmonger John McCain. Those who promoted “regime change” in Syria were rewarded only with ISIS and a mountain of corpses.
The failure of everything we have done in the Mid East in the last 25 years should be a continuing source of shame EXCEPT the decision to stay the heck out of the Syrian morass.
While I think McCain should long since have retired, I have some sympathy for him. Even if, as claimed, he was a crappy pilot, he did endure years of captivity and significant torture. It would certainly have bent my mind out of shape. Maybe that's why he's so quick to think that any problem can be solved by proper application of US military force.
As far as I can tell through the smokescreen of media coverage in Syria, he's way on the wrong side. The Christian (and Muslim) villager massacres perpetrated by the rebels are so far beyond the pale of acceptable, that they must be abandoned and squashed. Under Assad, it was repressive, but if you forswore politics, you were left alone, unless they mistakenly thought you were involved.
