Frankly, it may come to be seen as, in terms of bang for the buck, the single most effective use of US military funding in history.
Think about it: Russia went from being considered a peer-state of the US to the second most effective armycurrently conducting combat operations in Ukraine. That’s embarrassing any way you spin it. They have utterly destroyed any real vestige of conventional military power they had, and Ukraine is the one who shattered not only that reputation, but also the capability.
And not just in terms of physical assets - Putin called up training officers and sent them to the front. You just… you don’t do that. It means that instead of taking another year or two to train a new generation of officers to competence… it takes 10, and even then they’re not very good, because all the institutional knowledge those instructors had was lost. The only reason they’re even considered these days is because they’re a nuclear state.
