Sorry but in today's World it is impossible.
This is verging on the impossible to achieve, but if I was to try it I would have to adopt either a political or military approach. With a political approach I would form alliances with some of the world's top countries (USA, China, Russia, Japan, UK, etc) and persuade them I was better in charge than the incumbents and they should give me loads of money. Worse case scenario, they could just give me a little bit of a country and I could share it with the owners, maybe a piece of Switzerland might be nice!(but keep it quiet I am still in the planning process, LOL).
With a military approach, I would become head of an active military force. Once in full power of the military I would persuade all the army officials that the government was corrupt and we would be better off in charge. Of course I would have to bribe/blackmail them to do this!
I think I am best off sticking with my conquests on Risk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
