Ukraine is under Russian occupation?
It was generous of the Russians to allow American troops to be conducting military exercises there this summer.
If NATO is conducting military exercises in a Russian occupied nation, then perhaps the Russians are not so committed to going nuclear as you think, or want to convince Americans to fear.
Preaching fear and surrender to Russian conquest does show a lack of character, it is the same old, same old of the left, for at least 75 years.
You do not think Crimea is part of Ukraine?
