Christina Howitson Posted about 1 year ago How would you take over the world? One possibly way would be the Hoover method, named after J. Edgar Hoover, a man who was rumored to have dirt on everyone in politics. Imagine this on a global scale. Blackmail the world's leaders into allowing you to be involved in any or all decisions made by the leaders of whichever country. Because then you know what is happening in every country, and that sort of knowledge would be the ultimate power.
