Governor Rick Perry has been instrumental in facilitating the Trans-Texas Corridor and related toll roads, which many argue is an essential part of infrastructure for a North American Union (or community, if you like)-- that would integrate the economies, borders, police/military and even the currency (the Amero) of the United States, Mexico and Canada-- as laid out by the Council on Foreign Relations' Robert Pastor, as well as the Security and Prosperity Partnership of North America-- a treaty that President Bush signed with the heads of Mexico and Canada in 2005. In addition to general support and proposal of the plan, Perry publicly lobbied that foreign corporations developing the project be allowed to keep the plans secret.
