Free trade in America?

Washington Times:

The U.S. government's stubborn refusal to allow safety-certified Mexican trucks on U.S. roads, in violation of our North American Free Trade Agreement commitments, has spurred Mexico to impose sanctions on $2.4 billion in U.S. exports. An additional $800 million in exports are in jeopardy because of the damage our cotton subsidies inflict on farmers in Brazil. The European Union and Japan are weighing a further $500 million in sanctions over the biased and World Trade Organization-illegal formula the U.S. Commerce Department employs for anti-dumping calculations.
