Personally I don't think the West is "doing nothing". While they could do more (we're still a few days into this conflict, after all, i hope more will come), I fully agree with the strategy of full economic isolation, minimize resource purchasing from Russia (and move towards zero, which will take many years), sanctions, asset seizures of oligarchs, etc. as well as helping Ukraine with absolutely anything they need, but NOT direct military intervention. The moment NATO troops attack Russian troops (or the other way around), then we'll be in WW3. Up until that point, considering Russia has invaded a non-EU, non-NATO member, I think this is as much as the West should do. After all the US got away with something similar against Iraq with nothing more than vague lies about weapons of mass destructions and got zero punishment for it.
