"It works well enough" is a significant understatement. I think it would be more accurate (especially given the perceptions at the outset of the war) to say that it has worked significantly better than anyone expected. Ukrainian ingenuity is single handedly driving conversations about the "future of warfare" in capitals from Brussels to DC to Beijing.

This also misses the point imo. A simpler answer is "necessity is the mother of invention". There is value in a regime for peacetime. One is also a fool if they do not recognize needs change drastically in wartime. Two things can be true. The United States, like nearly all sensible nations, has almost always understood this and acted accordingly. On the other hand, nations that govern themselves as if they were on a perpetual war path are usually far less desirable societies. The idea that we need to speed rush "AI for killer drones" because otherwise we will find ourselves on the wrong end of an existential invasion are nonsensical. Americans would be far better off if our leaders and our people stopped acting like every potential conflict was existential.

There is no Russia on our borders. The only thing American adventures overseas have accomplished in the last two decades is making our country weaker.
