Well, for one thing, I won't tick anyone off. I'll use the easier ways, like bribery, or some other form of trickery. Anyways, not unheard of, but lesser known ones that are easy to take over with weak countries and rulers. Ah, alas, the evil doers part would not help. I'll have to befriend celebrities who I loathe so and after years of work get them on my side. I'm fairly sure there's plenty of Japanese people who would help me. Ya know, with their technology and some love power greatly. And the economically backwards would be solved by huge plans to make military pleasurable for people(i.e. decent salary, home provided, food provided, etc.). And the rest of the world will be taken over slowly, no doubt.
