However the US has already stated multiple times that it doesn’t care about international law and that Americans cannot be tried for war crimes and crimes against humanity, or they will invade the Netherlands. The ICC cannot even detain an American. This was during W Bush and his “war on terror”.
And then Trump recently reiterated it with a new executive order, imposing penalties and visa restrictions on people even helping the ICC to investigate Americans.
Just wanted to add that maybe the last thing that we did for the environment and that really worked was for acid rain in 1991. At least where I live.
A few years before that there was the Montreal Protocol that banned CFCs and helped to heal the hole in the ozone layer. I think.
