LOL, only in your narrowminded little world!!! Bwhahahahahaha!!!!!!!
Maybe not how it works in the sense that a group of gimps might attempt to lobby for charges of this sort, but dating as far back as the 1907 Hague Convention, as NesuD rightly states, require evidence of intentional targeting of civilians or plunder of territory for trial and eventually conviction.
Hell, it took the Hague years just to build what they thought to be a strong enough case against Milosovic--who blatantly targeted civilians in apparent acts of genocide. I would also point out that the munitions used in this war are the same we used in that war, as well as the first military action taken against Iraq--yet for some reason, the US was neither charged, nor found convicted of any war crimes.
The whole premise of this idiotic legal "strategy" by these imbeciles borders on the incredible: The US is guilty of war crimes because the weapons used cannot differentiate between civilian and military targets? As rudder already pointed out, neither can a simple 9mm round distinguish innocent or valid targets..........
It's OK flavio, your blind support of such ridiculous complaints is not anything we haven't come to accept from you and others of your ilk. You let your emotions get in the way history, fact, and precedent--all the while blindly accepting anything spoon fed to you from other simpletons with similar narrowminded sensibilities. But hey, you wouldn't be you if the otherwise was true.
