Good luck with that. Really...
So, you want a World-wide Nuclear War over this?
The US won't initiate a nuclear war. If Russia does, doesn't that say something about what a bunch of evil scumbags these people are?
“So, you want a World-wide Nuclear War over this?”
So, what you are saying is that Russia will initiate a “World-wide Nuclear War” if the Euro-Atlantic defensive alliance does not allow itself to be intimidated by Russian threats of nuclear war as Russia unlawfully conquers and annexes the independent and sovereign nation of the Ukraine in defiance of every norm of civilized law.
What is interesting about your comments is the way they ignore how the U.S. Air Force engaged Soviet-Russian fighter pilots in combat in Korea and Vietnam without nuclear war ensuing as a consequence. Likewise, the Israeli Air Force engaged Soviet-Russian fighter pilots in combat without nuclear war ensuing.
