here is a (admittedly whacky, but humourous I hope) theory: Ukraine and Russia are actually in concert with one another - the goal is to sap the US empire of its weaponry worldwide and thus make the USA weak enough to be conquered, mostly by using its own weapons against it. Or maybe China is involved on one side or the other, attempting the same goal. Imagine a m ilitary attack on US interests and the US being completely unable to respond due to lack of weaponry! :)

Or even better, maybe China will volunteer to build weapons for the US empire! I'm sure that generous financing would be offered and that in no way would the Chinese build and deliver toothless weaponry as did the French to Argentina, as the poor Argentinians discovered only when their exocets literally bounced off the british hulls during the Falklands War. :)
