The “War on Terror” has addled peoples minds so harshly that the notion that there is actually a legal way to wage war seems preposterous - however, there is a “legal means by which to wage war” which does in fact protect you, citizen, and you should learn about it - because when your representatives (and by proxy: you) violate those laws, you become personally liable for the repercussions that other victims will prosecute on you, and your nation state:

If ‘no bomb/missile ever is a war crime’, then .. there is no such thing as “terrorism”, either. (Although the argument could be made that there is no such thing as ‘terrorism’ at all, and that indeed, the word terrorism is merely a propaganda crutch used to justify atrocities against so-called ‘lesser cultures’ deemed inferior by the same institutions which used to use the ‘n-word’ to justify their atrocities in decades past, too, before that became difficult to do ..)

You can indeed commit war crimes with sticks too, though, incidentally.
