Bush admin was working on North American Union ("integrating" U.S., Canada and Mexico into one community)
A few years ago, one of the biggest conspiracy theories concerned a North American Union, an attempt to join the U.S., Canada, and Mexico together in some sort of community similar to the EU. An endless series of establishment hacks claimed that there was no such plan and that it was all just a paranoid fantasy.
As it turns out, those establishment hacks were lying (no big surprise of course).
A formerly-secret cable (recently released by Wikileaks) shows that the George W Bush administration was in fact working on a "North American integration" plan and was at least devising a strategy to sell Canada on the plan. The cable was sent by Paul Cellucci - former U.S. Ambassador to Canada - in 2005 (full cable here, via this):
See the last two links for more information, and after that you need to take action. There are at least three things you can do about this:
1. Bring wider attention to this issue and demand that your representatives look into any current plans to push for "North American integration". Don't think that just because Bush is out of office that means these plans have halted. In fact, back in February 2008, Barack Obama indicated that he'd continue Bush's "security" and "prosperity" plans. Recall also this Obama appearance and this. Obama is far-left in some ways, but he's a lot closer to Bush 3 than he is to the Communist that the tea parties dimwits think he is.
2. Enlist the aid of the Democratic Party base. The Canadian left is as concerned about these issues as some parts of the U.S. right. There's no particular reason why leftwingers should mock concerns about a NAU, other than the fact that they've been trained by their leaders to engage in such mockery. Try to "untrain" the smarter among them.
3. And, use the cable to discredit all those who mocked concerns about a NAU, whether on the right (Michael Medved and many others) or on the left (Chris Hayes and many others). Confront them in person on video, on Facebook or Twitter, or in comments sections and ask them to square what they said before with the cable. Here's a list of NAU deniers, and see the North American Union page for more. On a specific note, The Nation's Katrina vanden Heuvel is a member of the Council on Foreign Relations, one of the main proponents of "integration". Use that fact to portray Hayes and other Nation writers as simply tools.
