This was NATOs chance to prove they can do few shits and they blew it hard. Crimea was lost anyway, they should have sent troops and tanks into Donensk at an instant. The separatists would have layed down their arms or been severely demoralized to create further chaos and the situation could have been contained. They are brave, but they arent suicidal. Now you got these guys rising up all over Ukr cause they know Kievs troops wont be shooting at them a lot and NATO is busy picking its nose. The separatists are oldfashioned folk, from what ive gathered, u can make whatever the hell treaties u want with them, but unless u dont have fighters flying ontop of them and armor driving through their streets u wont gain their respect and nothing will stick.
And the russians advance would have surely been permanently stalled aswell.This isnt war(yet anyway). Both big players on the board dont want their troops killing eachother so it comes down to whoever drops their troops down to the area first gets it. Nobody unfortunately cares about the casualties of the ukrainians, but kill a few nato or russian troops and the shit would hit the fan bigtime to whoever is responsible. Sure russians would have been superpissed, but they are pissed now anyway. They'l just fabricate a reason to be pissed incase there isnt one.
