For all those who say they can't do this, I want to share my beliefs.
We are headed towards a global government. I don't believe there is anything that can stop it, and I'm not sure it needs to. It seems like a natural progression. However, as far as the corruption goes, none of it will fly until the world becomes a police state. Once that happens and people have the option of cooperating or being shot, people will sacrifice all rights and liberties for their own lives. That's where this kind of thing comes in. When every government on the planet summons its military and turns it on its own people, regardless of whatever reason they give{national security, protection, etc), then brute force will be used and people will fight and die at the hands of the military they spent millions arming or they will submit and accept their life as slaves to the state.
Just a matter of time til it happens. Look at China and Tieneman Square.
