Well we set off plenty of small (and not so small) ones in deserted areas in times past. I don't think many people today think that was a great idea. The UK is upping the ante by supplying spent shells containing uranium to Ukraine. Also not a good idea. That could plant the notion in the wrong kinds of brains that dirty bombs are OK, for example. This is turning into a proxy war in many regards. My dad always used to say that we needed Vietnam because it was the world's "safety valve." I think there's a lot of danger in that attitude, let alone a loss of humanity.
