America will do nothing except 'strongly condemn' what's happening, just like the rest of the world. The simple fact is that there is no real upside to risking actual war with Russia - that the Russians will dominate the Ukraine while walking away with a bloody nose (in the form of minor troop losses of its own) is a foregone conclusion. Without more, that's a localised conflict that Russia rather hilariously can try…
