And Russia does?! Russia?! With a GDP comparable to, say, Spain alone? Against the combined power of NATO?!
If NATO/USA doesn’t win in the first couple of weeks - inevitable loss.
"You cannot invade mainland United States. There would be a rifle behind each blade of grass." - Admiral Isoroku Yamamoto
It's claimed that the quote is bogus - that it is falsely attributed to Yamamoto. But that doesn't lessen its validity.
Regards,
“GDP” is irrelevant. In war it is industrial production that is relevant.
Credit default swaps, OnlyFans subscriptions, Uber secondary stock offerings, retail margins on imported Ch!nk crap - none of that is relevant to industrial production of military equipment for war.
The reality - it will take the USA until 2026 to install the new equipment to produce 6000 artillery shells per day.
That is longer than the Manhattan Project !
