Underneath the North American free trade agreement (NAFTA), Mexico truckers were to have been permitted to drive their trucks directly into the United States as well as avoid the costly and time-consuming border receipt that took place prior to the agreement. Though dreading job losses in the industry, the U.S. Teamster union thoroughly opposed the legislation. Though the group ultimately lost its fight, the United States still didn't give Mexican truckers freedom to transport their goods, pressure Mexico to institute retaliatory measures affecting $2.4 billion of goods distributed from the United States.

Why did the United States reply to the teamsters? Why are those pretentious by Mexico's retaliatory tariffs not lobbying congress for relief? Must the United States protect the teamsters at the expense of agricultural in California as well as Washington?
