We haven’t sent billions of dollars to Ukraine. We have sent them a couple of billion dollars, all the rest was in military materiel, almost all of which we had in long term storage, as we bought so much of it 20 years ago, we have newer & even better our second rate equipment is better than the Russian’s first rate equipment!
There are dozens of economic theories, but the sole one to be proven in real life are those of Keynes, which state when in a recession or even a depression, the government must spend & spend to keep the people fed & working, so they can survive & get out of the recession or depression. It worked at first for FDR, but then in 1936, he was convinced to cut back & the Great Depression got worse & it worked for Biden with the stimulus money that the government sent out out & the US fared far better than the fools in Europe who went all in on austerity!
