1) I'd spend a year writing a web-app to teach mathematics and physics, open-source it, run it on my own servers and lobby to have it used in high-school education. 2) I'd put more time into promoting awareness of Humanism and showing people that morality isn't restricted to the belief that an omniscient police agent is judging your every move. 3) I'd try to get NATO to play nice with Russia and after that get China on board as well. A USA/Russian/EU/Chinese block should be strong enough to stop nuclear threats and have the added bonus of getting us to Mars faster. 4) Having brokered world-peace and ensured continuity for all mankind, I'd chill out, read Ceasar's De Bello Gallico in Latin, master Bach's violin pieces at solist concert level, learn Russian and Mandarin Chinese, polish my French and grow awesome grapes for delicious wine.
