Perhaps that is why Cornyn keeps introducing legislation to implement it.
Senate Bill 2941. http://thomas.loc.gov/cgi-bin/query/z?c108:S.2941:
Highlights:
SEC. 3. PURPOSES.

SEC. 5. CONTRIBUTIONS TO THE FUND.
(a) IN GENERAL- The terms of the agreement establishing the Fund shall, subject to the limitation in subsection (b), require the Governments of Canada, Mexico, and the United States to contribute to the Fund.
I'd rather spend Mexico's money to build infrastructure in Mexico than our taxpayer's money. Unfortunately, foreign aid is a big budget item that won't go away. How much money is he talking about? I'd rather they spend it on a neighbor, and have it develop trade and wealth for us and them, than spend it somewhere else that offers no future benefits. At least it can be argued that this is an investment that will pay future dividends.
Cornyn's bill has nothing to do with eliminating borders or integrating three nations into one however.
