It will be difficult for the people who live in the West. Some will die - not that we all aren't going to die. But it will simply be a change of world ruler-ship. Putin or his successor will take over.
as longes china or usa don't get involved eu war it can be over and after few missiles attacks in Europe the peace talk can be starting fast.
And it doesn't take long i guess in few hours the war will be over becouse missiles are fast and destroy fast so then USA and russia probably the trump Putin meet and talk about peace conditions.
Once western countries see war in real then they belive in possibility of war right now people don't understood that war could touch even locations where it's impossible and are important people then world will wake up and see that war is not way becouse it might not stay inside the war zone countries it's like fire wich could go out of control.
You better not start fire at all because it could go out of control right now countries playing with fire.
