We should stay out of Syria then, as the reasoning for war is 'peace and love'. I'm not prepared to die in a war with Russia over Syria however horrible it gets for the civilians, are you?
Since the likelihood of that happening is remote, I've not really given it much thought to care.
The guy is relatively well educated, certainly moreso than most, he's not a buffoon, why on earth would he trade off his life (quite potentially), with that of a few hundred of his soldiers and a few more weeks (not to mention the backing of Russia) to flush out some rebels? It's absurd.
Why do men in power do anything that they do? More so, why do dictators in particular? And why do they cling on like they do? Power and greed, like any other is why. That and ego.
The way some people seem to paint these leaders as saints is beyond me. Trump is almost always described as a tyrannical monster though...
