First, I'd get developing countries and give them a leader, me or someone who I trust, and Hope for a life that's way more awesome and learn their ways as to make it look like I want to make their lives better and not to conquer. Then, I'd bring technology over with boxed electricity and teach them about that. After, band all them together and start grabbing lesser contries a swiftly as possible. I should have Asia by now so I'd go get Europe and Africa. I now have all of the Eastern Contenient. With my awesome fury, I get Canada and South America, slowly getting the US to make them suffer for their horrible health care and fruitless campaign against everyone. Australia and Antarctica would submit sooner or later, so I don't need to worry about them. Even though the ARE awesome. With everyone united, I've stopped major war and just left street fight and gang rumbles, that my Cyborg Police can stop easily.
Doesn't sound to bad.
