People don't normally view serving in their country's military as a war crime. By your standards 99% of anyone is who has ever been in any modern military should probably be in jail, and that's not going to happen so why stress your little head about it.
Any person who by now claims to be uninformed about the American military commitying war crimes either has a literal mental disability or is willfully ignorant.
Edward Snowden, Julian Assagne and more have proven the crimes the US military is committing and hiding.
Same for the IDF. They are posting their war crimes on TikTok. Are you saying people do not know? They approve of it. Israel will not jail these people because it is a Nazi state. But they should be jailed.
