So does that mean we can take action against the Mexican government...who is violating our law by aiding illegal aliens in sneaking into our country....
I think it would be easy to lose ground if we try to blame this problem on folks over whom we have very limited influence.
I don't see our illegal immigration problem as a fight between the United States and Mexico. I don't see the problem as a dispute between the American and Mexican peoples. I think the struggle is a domestic struggle between, on the one hand, American taxpayers, American employees, and American employers who comply with our laws and, on the other hand, those American employers who violate our laws and thereby impose huge costs on the rest of us.
We really don't need any cooperation from the Mexican government or from the Mexican people. We just need our own government to faithfully execute our immigration and employment laws. When compliance with our laws becomes cheaper than violating our laws, the problem will solve itself.
