The USA has never fought Russians.Oh, and by the way, I have no current problem with Russians as I find this current peaceable situation much more interesting than fighting them. The thought of cold/wet European winters and cold food is not my cup of tea, period. Been there and done that.
If we had they probably would have kicked our azz.
There are more of them.
They have more tanks.
They have more arty.
They have just as many if not more planes.
Their planes are built tougher than our planes.
Their pilots are just as good as our pilots.
They live in Europe and we don't.
So they can resupply easier than we can resupply.
All that they need to do is cut off our supply lines and then our soldiers are up sh!t's creek.
