You mean like Czechslovakia did in 1968, right? Or like Hungary in 1956, right?
I'm sure they appreciated all the help from us when Russian tanks rolled through their streets.
Considering Poland was threatened with nuclear attack; they proved their test of courage -- once again. We would be penny wise and pound foolish to skimp on military equipment/training. Sure, we'd save a little money now. People need to ask themselves what the cost would be if Russia keeps expanding before we do anything. They'll suck Europe's blood like a vampire, grow strong, and then where will we be?
There will only be the pathetic hope that Russia and China might be rivals. If not, the world will be in greater danger than when the Axis Powers were united in WWII.
