I agree with you, USA or even NATO is not capable of invading Russia, but that is not their goal, they want to Ruin it economically, and cause an jprising, and change of power, where they will be calling thw shots, like they are in Europe, western Europe is just a US proxy.The US has not had to contend with attacking a strong tier 1 military in a long time. They were defeated in Afghanistan most recently. If they attacked a tier 1 power like Russia, their carrier groups would not be able to get into strike range without being sunk. It would not be pretty. Best to not think about it
so all I am saying is that USA is currently a military Behemoth, that Russian and China combined, cant even hope to tackle, Russian and Chinese Navies Dwarf the US Navy in numbers and technical capabilities.
