John Hawkins tries to take on some of the nonsensical rumors swirling about that the Bush administration is trying to merge the US into some sort of superstate. I'm afraid that he's not going to have much impact. As he notes, it's difficult to reason people out of ideas they weren't reasoned into. He tries to address the rumors head-on, but his best point is probably this:
...then believe your own knowledge of how the U.S. Government works. To merge the United States into a North American Union would obviously require a whole host of Constitutional Amendments. In fact, so many would be necessary that the only possible way to accomplish it would be through a Constitutional Convention, an event that hasn't occurred in over 200 years and that would require the support of 34 state legislatures to be possible. So, even if George Bush or any other U.S. President were so inclined to create a North American superstate, he would be powerless to do so unless he were able to rally 2/3 of America's state legislatures to his side.
People, even if this was going to happen, it's not going to happen without anyone knowing about it.
