Agree which is what most people here miss. This shows the power gap between US and Russia. Contrary to what many believed in the past that Russia was still a near military peer (well, behind US but not that far to this extent) to the US.
THIS CONFLICT has shown that Russia is nowhere near a military peer to the US. in fact I believe the US is just taking her time to slowly but surely drain Russia to a point that Russia will be inconsequential in any future conflict after they are done with them in Ukraine(the war will probably last another couple years by which time Russia will be another shadow of nits former self).
Had the US really committed itself completely in helping Ukraine(I.e focus even half of their might) Russia wouldn't have been able to sustain this war for even a few months to be honest. The thing is despite US hostility towards Russia, the Russia doesn't see Russia as a credible real threat to herself. Russia is just seen as an irritant to the US to be honest. Reason the US and its political/military establishment isn't really focused 100% on dealing with Russia in Ukraine. The US knows its real long term threat to its hegemony and world supremacy will be(is) China. Russianis just an afterthought and rightly so. Had China be the one fighting to invade another country(like Russia did with Ukraine) then you can be sure that the US reaction will be totally different. All US political, military and industrial establishment will be clamouring for the US to go 100% on a war footing, ramp up its military production and they will have provided all necessary military aid they could to that country and provide unconditional unlimited military and economic aid to that country to country to fight off the Chinese. So the US would have acted completely different and fully committed, since they view China as their principal number 1 threat today and in the coming decade. So in this regard I will say Russia is also lucky, since without the Chinese threat, US support in Ukriane will be different and even more precarious for Russia..
