Well you still have all those Mexicans sitting on death rows in the United States. so Mexico could do two things, suggested before:
1. invoke the Arbitration Clause of the Treaty of Guadalupe-Hidalgo;
2. negotiate and conclude an international executive agreement with the United States government settling this entire dispute that could then be enforced upon the States of the Union holding Mexicans on death row under the Belmont and Pink cases.
It should also continue with its new case at the World Court calling for an Interpretation of the Avenna Judgment.
It is truly unfortunate because as documented in my book Foundations of World Order (Duke University Press: 1999), the World Court was originally the idea of the United States of America going back to the First Hague Peace Conference of 1899. How far we have sunk during the past century, and especially under this particular Administration.
