The US gets to test new missiles, and Russia gets to test its new missile defense. Both sides learn each other’s ability. Everyone is a winner.
We are in a strange situation where there has been a somewhat combined proxy war against ISIS in syria, the general "left" of the country ignored that and shouted we should do more when it was at its height and we now have a situation where Assad is again "potentially" using chemical weapons against its own citizens.
It was only a year ago that Putin and Trump was apparently in cahoots, for some it has become anything the Tories or Trump say is automatically wrong on political grounds, despite being in favour of such intervention beforehand (ifysim)
We do not want an Iraq2 on our hands, but its a situation for the west of damned if you, damned if you don't, whatever situation is, it entails that it will be political scoring point in the future.
It's a shit show all round, and we will never know the ins an outs of the situation, ever side has an agenda to push.
Sorry, just a rant
