Bush's answer was:

"We represent three great nations. We each respect each other's sovereignty. You know, there are some who would like to frighten our fellow citizens into believing that relations between us are harmful for our respective peoples. I just believe they're wrong. I believe it's in our interest to trade; I believe it's in our interest to dialogue; I believe it's in our interest to work out common problems for the good of our people.

"And I'm amused by some of the speculation, some of the old – you can call them political scare tactics. If you've been in politics as long as I have, you get used to that kind of technique where you lay out a conspiracy and then force people to try to prove it doesn't exist. That's just the way some people operate. I'm here representing my nation. I feel strongly that the United States is a force for good, and I feel strongly that by working with our neighbors we can a stronger force for good.

"So I appreciate that question. I'm amused by the difference between what actually takes place in the meetings and what some are trying to say takes place. It's quite comical, actually, when you realize the difference between reality and what some people are talking on TV about."

Harper joined in. There's not going to be any NAFTA Superhighway connecting the three nations, he said, and it's "not going to go interplanetary either," he said.

Harper said the SPP discussions that were held concerned such pressing issues as jelly beans. He said the business interests expressing their desires for progress on the SPP noted there were different standards in the United States and Canada, and there was a discussion about whether those standards could be made uniform for the U.S. and Canada.

Bush's comments echoed the comments published just a day earlier in the Ottawa Citizen by David Wilkins, the U.S. ambassador to Canada.

"While conspiracy theories abound, you can take it to the bank that no one involved in these discussions is interested in, or has ever proposed, a 'North American Union,' a 'North American super highway,' or a 'North American currency,'" he wrote.

"The United States, Canada and Mexico are three distinct, sovereign countries that practice democracy differently," he wrote. "Each proudly defends its own interests. But our leaders also recognize that we share a continent in this post-Sept. 11 world, where terrorism is but one threat. We have a vested interest in working together to prevent potential threats outside North America – like those posed by pandemic flu or improperly labeled foods, for example – from penetrating our borders.

Wilkins wrote that the nations also are "exploring ways to detect radiological threats and coordinating emergency efforts along our borders in the event of a man-made or natural disaster. It just makes sense when you share thousands of miles of common border to share a common emergency-management plan."

He said another goal is to reduce the cost of doing business across national borders.

From the The North American Competitiveness Council (NACC), statement:
Food safety and border security also were discussed. "Our governments will continue to address the safety of food and products imported into North America, while facilitating the significant trade in these products that our countries already have and without imposing unnecessary barriers to trade," the leaders said.

"It is sometimes best to screen goods and travelers prior to entry into North America. We ask our ministers to develop mutually acceptable inspection protocols to detect threats to our security, such as from incoming travelers during a pandemic and from radiological devices on general aviation," the statement said.

"The cooperative efforts under the SPP, which can be found in detail at www.spp.gov, seek to make the United States, Canada and Mexico open to legitimate trade and closed to terrorism and crime. It does not change our courts or legislative processes and respects the sovereignty of the United States, Mexico, and Canada. The SPP in no way, shape or form considers the creation of a European Union-like structure or a common currency. The SPP does not attempt to modify our sovereignty or currency or change the American system of government designed by our Founding Fathers."

One frequent claim of the conspiracists is that the NAU will override the US Constitution and replace our court system ...

The basis for this claim is the presence in some free trade agreements like NAFTA of special courts which are intended exclusively to hear trade disputes which cross international borders. These special courts have very clearly delineated powers and in no cases do they include appeals from US criminal courts or the ability to override domestic law within the United States.

Another typical misrepresentation arises from proposals for regional security. For example, the SPP proposes establishing a regional security perimeter to screen dangerous travelers before they enter any of the three North American countries, an obvious way to address the problem of potential terrorists sneaking over the huge northern and southern borders of the United States by catching them at their port of entry. The conspiracists overlook the legitimate security purpose of this idea and instead interpret it as a plan to get rid of borders between the US, Canada and Mexico so that there will be an unrestricted flow of Mexicans into the US work force. Administration proposals for guest worker programs fit right in with this and are seen as the first step towards opening the borders and welcoming in a flood of immigrants. Never mind that such a program is designed primarily to make sure that immigrants are identified and controlled and can be limited and removed more easily as is impossible under the current system.

Trade agreements are also a frequent target of the conspiracists. They see every effort to make trade with Mexico easier as a plan to take away US jobs or lower wages. What's really going on, of course, is an effort to build up the economy of Mexico while at the same time holding down inflation in the US.

North America’  SuperCorridor Coalition, Inc.

North America’s SuperCorridor Coalition, Inc., is a non-profit organization located in Dallas, Texas, dedicated to developing the world’s first international, integrated and secure, multi-modal transportation system along the International Mid-Continent Trade Corridor to improve both the trade competitiveness and quality of life in North America.

For over ten years, NASCO has been developing a strong coalition of cities, counties, states, Canadian provinces, and private sector companies to lobby for federal funding and promote a "SuperCorridor" to address the transportation, trade and security needs of the three NAFTA nations.

We have assisted in the lobbying effort to bring hundreds of millions of dollars to the NASCO I-35 Corridor, resulting in High Priority Corridor status for I-35 in 1995 under the Intermodal Surface Transportation Efficiency Act (ISTEA). In addition, we successfully assisted in lobbying for the creation of two new categories under the Transportation Act of the 21st Century (TEA-21) – the National Corridor Planning & Development Program and the Coordinated Border Infrastructure Program.

NASCO also successfully lobbied to take the Highway Trust fund "off-budget" which resulted in increased transportation formula funding for NASCO's corridor states.

NASCO has received $2.5 million in Congressional funding from the United States Department of Transportation (USDOT) for the development of a technology and tracking project.  The project will have a team approach, using members of NASCO as the primary participants in the project, to the extent possible.  NASCO believes the deployment of a modern information system will reduce the cost, improve the efficiency, reduce trade-related congestion, and enhance security of cross-border and corridor information, trade and traffic.

The NASCO "SuperCorridor Caucus" was formed on Capitol Hill to promote corridor development and to help secure NASCO legislative initiatives in both the authorization and appropriation processes.

NAIPN another sub-creature of NASCO

North American Inland Ports Network (NAIPN)

 NAIPN is a working group in North America's SuperCorridor Coalition (NASCO). NAIPN advocates the interests of Inland Ports along the Mid-Continent International Trade and Transportation Corridor (MCITTC) and supports NASCO's mission to strengthen the Secure, Multi-Modal Trade and Transportation System.

What do they mean by "inland ports"? well it's visible right at this link: http://www.nascocorridor.com/naipn/index.html

  http://www.nascocorridor.com/pages/federal/special_projects.htm

NASCO supports Sec. 1825, the Multi-state International Corridor Development Program, new language initiated by NASCO, authorized in 2004’s Senate passed version of S. 1072, the “Safe, Accountable, Flexible, and Efficient Transportation Equity Act of 2004” and asks the House to consider supporting this language in their bill or to accept the language in conference.  

This program would develop international trade corridors to facilitate the movement of freight from international ports of entry and inland ports through and to the interior of the United States.  NASCO supports the Senate language regarding selection criteria for corridors including:       

1. Must have Significant levels or increases in truck and traffic volume relating to international freight movement [NASCO truck traffic has increased 42.6 percent from 1996 to 2001 ]
2.  Connection to at least 1 International Terminus or inland port [NASCO has an international terminus in Laredo/Nuevo Laredo; Manitoba; and Windsor, Ontario and serves 3 inland ports including Detroit; Laredo and Pembina, N.D.]
3.  Corridor must traverse at least three states;[NASCO traverses 11 states including Texas, Oklahoma, Kansas, Missouri, Iowa, South Dakota, North Dakota, Minnesota, Michigan, Indiana and Illinois ]  and 
4.  Identified by Section 115 (c) of the Intermodal Transportation Efficiency Act of 1991 (Public Law 102-240; 105 Stat. 2032) [NASCO is High Priority Corridor #23]

However, the Senate passed language did not authorize funding for this program it was estimated that the corridor needed $2 billion per year in infrastructure improvements over an 18-year period.

Myth: The U.S. Government, through the Department of Transportation, is funding secretive highway projects to become part of a “NAFTA Super Highway”.

From the link provided above:
"While conspiracy theories abound, you can take it to the bank that no one involved in these discussions is interested in, or has ever proposed, a 'North American Union,' a 'North American super highway,' or a 'North American currency,'" David Wilkins, the U.S. ambassador to Canada..

Canada's Prime Minister Stephen Harper joined in. There's not going to be any NAFTA Superhighway connecting the three nations, he said, and it's "not going to go interplanetary either,"

  From About NASCO: "NAFTA Superhighway" - As of late, there has been much media attention given to the "new, proposed NAFTA Superhighway".  NASCO and the cities, counties, states and provinces along our existing Interstate Highways 35/29/94 (the NASCO Corridor) have been referring to I-35 as the 'NAFTA Superhighway' for many years, as I-35 already carries a substantial amount of international trade with Mexico, the United States and Canada.  There are no plans to build a new NAFTA Superhighway - it exists today as I-35.

Bush's comments echoed the comments published just a day earlier in the Ottawa Citizen by David Wilkins, the U.S. ambassador to Canada.
