The former Blur guitarist, speaking in a new video alongside Pete Doherty for political/music organisation Instigate Debate, said that he wants the US to "start again".
"Part of me wants to kind of clear America like an old overgrown field that needs the stubble burning and start again," he explained. "Just keep all the nice Americans somewhere while we do it. I think there'll be a lot less oxygen being used, a lot less greenhouse gasses."
He added: "That's my little dream fantasy, that they have no importance in the world, they're not some sort of power, they think they're policing the world, and we can actually get back to how it used to be when us and Persia were good mates."
Coxon and Doherty also discussed topics including corporations gaining increasing monopolies of the media. The Babyshambles frontman questioned why anyone would want to operate a vast media empire.
"Why would anyone want to own all that? It's a bit perverse," he ventured. "Writing s**t about me and my house, saying I've got a smelly house. Which I do. It's my business. Why don't you use the money for some cleaners and solve the problem?"
