It's not about "white feathers", it's about International Politics.
politicians may be devious and self serving, but they are not stupid.

Cameron and the Blairites know very well that our engagement will make no material difference to the situation in Syria and certainly will not make us safer at home. It is about constructing an alternative coalition to ensure that Russia and Iran do not end up as major powers in the area.

We cannot afford to play games with these Jihadi lunatics, we must support Assad against all opposition, create one united coalition which can push them right out of Syria and Iraq. This is what Mr Corbyn was suggesting.

Co operation on this issue may lead to a bit of realism returning to International Politics.
