Actually Pres. Bush has EVERYTHING to gain from something like 9/11. He was able to pronounce a "War on Terror" and instill fear into the hearts of every American citizen. With this fear he was able to pass legislation like The Patriot Act and FISA which take away our Constitutional rights and allow the government to have more and more control over its citizens. He was able precipitate a war and further his families agenda to create a New World Order... and don't think that the term "New World Order" is some conspiracy theorist crazy talk... both GWB and his dad have expressed quite publically that they would like a NWO.
The government has plenty to gain from it. Former President Bush has nothing to gain from it. He didn't have to instill fear into our citizens, it already happened from 9/11. He could've never declared a War on Terror and there'd still be fear. But in the same manner, this War On Terror plummeted his approval ratings. It made him look like a failure and a joke to America. Bush is no more than a meme now. And before this debate comes up, his war on Iraq was basically required in the treaty post-Persian Gulf War when Hussein denied access for America's search; whether or not there were WMDs, America had signed up for the responsibility of that war long before it happened. The possibility of WMDs was brought up solely to get the less intelligent to back the decision that was already agreed upon years ago.
As for a NWO, I really want to know what the government's idea of a NWO would be.
