Ok,you start with Canada.No one would ever suspect Canada.You take over Canada,totally in secret so the rest of the world has no idea.Then,once you're secure there,you use Canada as a base of operations to start on the rest of the world.Because Canada is so peaceful,the first place you attack won't see it coming.I'd go after Asia first,since they supply most of the world's technology.Then,when the rest of the world is reeling from surprise,and you've got Asia under your thumb,you go after the countries that supply the oil.If you cut off the tech,and the oil,and many other imports,then America would be weakened and you could go after them.Once you capture America,you're pretty much set to take the rest of the world...
I've put a little too much thought into this...
Finally, a topic I know all about. This is a topic that I have discussed with my friends frequently. If I were going to take over the world, then I would do it Hitler style. It would have to be in a time period when everyone thinks that we need change, so I guess I'll be waiting for a few years, but once I have my chance, then I'll strike. I'll slowly advance in importance until I rule the country. Then I'll make laws stating that the leader of the country cannot be changed in times of crises. (To secure my position for a couple of years. Even if I have to make up a crisis just to keep ruling.) Then I'll make a couple of laws that basically state that I can pass any laws that I feel are the best solution for the nation. With a majority of votes from the government, of course. After that I would allow other nations to get in on the solution with the offer that I can fix their problems, too.
Once I do this, I'll turn this town upside down. The world would basically be a huge version of China, where the solutions to problems are found and quickly eradicated. The people justly punished. ( I mean justly punished, not like that whole baby food solution thing where the people were killed for a mistake. That's kind of harsh.) And the world would become a better place. But only under my rule. This plan will only work if I do it. *eyes those people agreeing*
