Exactly. Human nature has shown us over and over that its basically impossible. Global Elite aside, its an Evil world we all live in and if America wasn't the ones calling the shots, I'd hate to think of who would be. 
China are the world's next great power, if not the current Global Force, Americans ignore China a lot in terms of threat, but things have changed since the Korean War - China have technology now, and not small grunt army of donkeys and knifes. China have long long history of warfare and are pretty good at it, they will wait till America is at their most vulnerbale, and Thwack! America wont even know what hit him, and next think you know, whites are the minority, and the Chinese have a re-settlement colony for continued expansion - lots of space for Chinese factories in the States - plus the average Chinese person is 1/3 rd the size of the Average Fat Arsed American, so land requirements for food production will be minimised for a start. Tibet is just a testing ground for larger, more resource rich countries to be invaded - how to occupy with minimal world disruption - the Chinese will show the States the art of Warfare, I am sure of this.
"Most experts would define 'threat' to mean a combination of capability and intentions. There's no question that China is building up its capabilities, but China
has displayed no intentions of using those capabilities against the United States."
