If I could change one thing, I'd travel back in time and make the cameras in the Whitehouse capture how the plans to go to war with Iraq actually happened, and then in advance hire Bush the best lawyer possible to prepare the case which would be sure to get him off the hook, no matter how desperate his case was. Then, when the charges against him would be dismissed, in spite of the heavy evidence against him, people would see sense, say to hell with it and never again expect any seriousness from Washington, and elect Conan O'Brien President instead. The legislative branch would be dismantled and then reinstated as a weekly rotation between the major newspaper's columnists and literture critics for science fiction. Lawyers would be busy trying to reestablish their credibility after the Bush "incident". World leaders would be invited to settle their issues at Camp David amongst a camera crew, a live audience, and a band to accompany the threats and promised reprecussions. And no issue would stay unresolved for more than 30 minutes, so as to fit the TV- schedule. Musharaf would be called up in the middle of the night to answer questions about his Afghanistan policy and his haircut, and Ozzie Osbourne would be Brien's political adviser - Colin Powell and Rice would frequently be called in as the expert panel to settle why the President's demands for steps in the Middle east process would be sensible, and as interpreters for the vice precident.

But I might go with beer in the faucets, that was a very good suggestion.
Good thing greed and selfishness was removed as well.
