Be a billionaire, take over the world. Joe just needs to work his way up to being on the board of directors for several very large companies such as Exxon Valdez, Alcoa, Apple, Google, Microsoft, etc and he'll be a very rich man, very quickly. Being in a position of power like this is definitely doable in 25 years or less.
If Joe is a psychopath, then he's well on his way to being CEO.
British journalist Jon Ronson immersed himself in the world of mental health diagnosis and criminal profiling to understand what makes some people psychopaths — dangerous predators who lack the behavioral controls and tender feelings the rest of us take for granted. Among the things he learned while researching his new book, “The Psychopath Test: A Journey Through the Madness Industry”: the incidence of psychopathy among CEOs is about 4 percent, four times what it is in the population at large.

Because of the political attitudes and histories of the countries listed in the OP, no obvious political union will be possible. Given the animosity between the US and Russia, and the radically different cultures, those two countries will never become a single political entity. Similar animosities exist between all the listed countries. Besides, unifying is an incredibly difficult job and there's better ways to do it.
What you want is a plutocracy where the rich people govern either from behind the scenes or in the clear. Plutocracy offers the advantage that political control comes from the control of wealth which may freely cross political borders rather than the assent of people in a given geographic area. Controlling large amounts of wealth also means that you can buy whatever legislation you want to give you further advantages or immunity.
Note that the United States, in the opinion of many, is already turning into a plutocracy.
