A Mexican senator has called for Mexico to reopen all its border disputes with the United States in order to oppose the Trump administration. (Hat tip: Mexfiles.) According to Senator Patricio Martínez — who formerly served as governor of Chihuahua, a border state — the Mexican government should insist on the transfer of about 400 square kilometers that Porfirio Díaz asked for back in 1890. “Díaz was unsuccessful, but Mexico should send a new diplomatic note to Washington to rectify the border limits,as defined in the two 19th century treaties. If Trump refuses, Mexico should seek the intervention of the International Court of Justice, in the Hague.”
Senator Martínez is planning to fund a commission “to document what has been known since the time of Díaz, that the treaties of Guadalupe Hidalgo and La Mesilla, which set the border between the two countries are not applied, and there are differences and errors in favor of the United States which must be corrected.”
That would be a great plan if there were any evidence that the United States and Mexico had any outstanding border disputes. Sadly, there does not seem to be evidence of any such conflicts, not since the Boundary Treaty of 1970. The idea that the U.S. is sitting on 400 square kilometers of Mexican territory would be an alternative fact.
