the case of Hispanics and Native Americans, it's not even clear that there was an offense. Consider: Texas legitimately revolted against Mexico and established an independent republic. Mexico can't exactly complain about that, because Mexico had just recently revolted against Spain. Then Texas chose to join the United States. Texas has a disputed border with Mexico, and the Mexican War erupted over that disputed territory. Mexico lost the war, and American troops were in Mexico City. America could have kept all of Mexico; instead, America returned half of Mexico and paid $15 million to settle Mexico's debts. Arguably there is a theft in here somewhere, but it's hardly clear. Moreover, a treaty was signed between the two countries establishing the new borders.
