Block the plan? Excuse me? The nerve...
"We learned to believe in the United States. We have a binational life," he said of Zacatecas, a state that has been sending migrants north for more than a century. "It isn't just a feeling of rejection. It's against what we see as part of our life, our culture, our territory."
Gee, that's nice but the part about a "binational life" and seeing the USA as part of "our territory" is exactly the problem we have with the illegal immigrants and Mexico.
Understand this: The USA is NOT a part of Mexico and Mexican nationals who come to the USA illegally and a live a life here, breaking the laws of the USA and in doing so steal from the citizens of the USA are the reason why we want a border fence/wall. Securing our borders and enforcing our laws is the duty of government officials.
Must be planning to file a suit in the Hague like the Palestinans. Notice Israel told them to pound sand over this and their wall seems to have solved a lot of problems.
