Some Mexicans are proposing to remind Mr. Trump exactly what country was the first victim of American imperialism. They are calling for a lawsuit that would aim to nullify the Treaty of Guadalupe Hidalgo (signed on Feb. 2, 1848), in which Mexico — invaded by American soldiers, its capital occupied, its ports and customs stations seized — was forced to accept the American annexation of Texas and concede more than half the rest of Mexican territory, now including most of the states of Arizona, New Mexico and California.  See full story in the New York Times.
