I want to declare myself an almighty and divine being and see how many worshipers I can get, then use them for a government coup. After I've taken over the country's government I can control the military and commence the conquering of the world. I'll start with allied countries first since they won't expect it; I'll surround them while they're off guard and order them to give in peacefully. After I control them they won't be able to refuse giving me their military forces for an unworthy cause. The rest of the world domination plan should fall into place nicely afterwards.
