It's good we stayed out but we still have US bases all over the UK & we remain an integral part of the US comms network (and as such remain a nuke target), so unfortunately it's not over yet.
this really isn't going to lead to world war 3 though... A russian naval base in the north of syria is important to russia symbolically, but not actually worth risking a nuclear exchange over.
It would be lovely to sort these things out, but the west is in dire financial straits and really haven't we learned that intervention never really works and blowback is inevitable.
i find it funny that most people who support a strike don't have to ride the london underground every morning
