> I wonder if anyone is going to learn a lesson about overregulation.

Seems unlikely. Regulation and Health & Safety are both societal luxuries, which only happen once societies are stable and prosperous enough to start valuing human life beyond its ability to perform labour.

The moment the bombs start dropping, the time for luxuries also stops, and the value of human life drops to value a person can produce defending their society. There isn’t the money or resources for anything more than that.

The US (most developed democracies) places an extremely high value on the lives of soldiers, because dead soldiers in foreign wars does terrible things to politicians in power. Paying 1000X more for the same tech as Ukraine to minimise the number of service members killed using it, is a pretty small price to pay.
