TLDW: He was totally down with neutron bombing most of the world's population until Ted Kennedy made a move on his daughter. That was when he decided the illumunati had gone too far and must be stopped.
I completely disagree. Didn't Star Wars teach you anything? The New World Order IS the Empire. Not that I base my beliefs off of a popular movie, but it's the best example I can think of as to why the NWO is a bad idea.

The destruction of Alderaan is just a larger scale version of what we regularly do in wars by targeting civilian populations for intimidation. If the Empire had banned slavery endemic under the Republic, or used it's power to stop ongoing genocides, the actions of the rebels would be simple terrorism and sedition, not heroism. That's often why large-scale governments form, to stop local abuses of power.
Conspiracy theorists give the government way too much credit.
