It's not insane if you consider the West is doing the very same thing (committing war crimes) but Western media doesn't report in the same way about it. Just check what the Americans did in Iraq, whom they deliver their weapons in Syria to, ...

One thing I always ask myself:

The war in Syria is basically won by the regime, so why the heck would they now resort to bombing hospitals and C-weapon attacks on the population? It just doesn't make sense so that's why I am very cautious here.

This is not to say that Russia is good and the US is bad, it's just that "The first casualty of War is Truth"
