"Mexican Cession (1848): The most significant event was the Mexican-American War (1846-1848). Mexico lost the war, and through the Treaty of Guadalupe Hidalgo, it was forced to cede a vast amount of territory to the United States. This territory included present-day California, Nevada, Utah, most of New Mexico and Arizona, and parts of Colorado, Wyoming, Kansas, and Oklahoma. Texas had already declared independence from Mexico in 1836 and was annexed by the U.S. in 1845, a major cause of the war."

"Displacement and Dispossession: While the treaty promised to protect the property rights of Mexicans who stayed, in practice, many lost their land through legal maneuvering, fraud, or outright violence. This forced displacement would have driven some south to Mexico."

Whatever doesn't belong to Mexicans surely belongs to Indians.

Sounds like a good place to start. After that - Australia and Canada. Once that's done let's do Israel.
