> Like the US is much better at this, throwing trillions of public money in weapons while they can't seem to afford free public healthcare.

The US can afford free public healthcare. It could probably afford free public healthcare with its current public healthcare spending (per capita it spends far more than most developed countries providing that, and per GDP it spends a similar amount), but instead it's spends hyper inefficiently so as to maintain a private healthcare system that costs even more on top of the public system.

Weapons are irrelevant to that, though the US spends too much (and too inefficiently) on those, too.
