For one, how the living fuck would ANYONE get climate change from anything you just wrote, you absolute donkey?
For two, you're not a U.S. citizen, so it's not just your country of origin, it's your country of nationality. And people who live in glass houses (especially ones that threaten to nuke their neighbor (who is also a nuclear power)) probably shouldn't throw stones (and because you're so stupid, I'll explain that the stone you're throwing is that America will somehow cause the end of the world, which is less likely than you fucking abject morons accidentally starting a nuclear holocaust over 500 feet of Kashmir).
