Probably the US won't send in the troops in a manner that would be seen that way by Russia.
It's time for some creative thinking though, because the Ukraine is finished and the UN may not come to the rescue.
All the agreed upon limitations by both sides can't be just dumped aside. They were and still are, limitations that preculde the need for a nuclear war.
What can America do for the Ukraine that would be agreeable enough to Russia, so that limitations are still observed?
In any case, we need a definitive answer on whether the UNGA is going to do America's bidding?
The huge majority of the world's people have turned against America's proxy war.
Can America depend on 'country' count alone, and does America even have that majority?
