Their merchant fleet can move 100 million men??
10,000 men x 6,000 ships = 60 million men. But you can put a couple million in the USA ahead of time, a couple million in Mexico in care of the drug cartels, and a couple hundred thousand scattered around Canada. NUke the west coast in surprise attack. nuke the USN pacific fleet in surprise attack. If 4000 aircraft in Ukraine, and 4000 are in Taiwan, what exactly is left to defend the west coast? A million flood up from Mexico, and Long Beach and Los Angeles start unloading container ships full of men and material. With all our armor in Ukraine, and all our ammunition already spent, its a few thousand National Gaurdsmen, plus the reserves, and .223 rifles v. whatever they can land in Mexico and California. And dont’ leave out they would be attacking our forts and munition supplies from the kick-off.
Russia_China believes they can win WW3, conquer NATO, conquer USA.
