Mexico was a conquistador colonial state. They had no claim on any of their modern day United States land. That land should also be Native American Territory, along with Florida.
Latin America countries has less severe history of racial genocide compared to Canada and the USA which makes them less priority for anti-colonization. Mexico is now under the control of mostly mixed Indigenous people unlike the USA and Canada that massacre their mixed Indigenous population along with the Indigenous people. Mexico also did not seem to enslave and massacre their Indiegnous people in fake schools in a large scale during the Cold War unlike the USA and Canada.
AFAIK Mexico is also a settler colony, there’s presumably a landback movement there as well
Mexico is NOT a settler colony. The Mexico of the 1800s was in constant war after many attempts of the US, the spanish and the french to recolonize the country. It was born out of the struggle of indigenous people against spanish colonization. The many contradictions of the time led to a century of chaos across the country and constant invasions by the US, the spanish and the french and each would be met with fierce resistance by the people and leaders like Benito Juarez which himself was an indigenous man. This chaos would only end in the violent “peace” of Diaz and the mexican bourgeoisie in collaboration with the international bourgeoisie of the US and France, but that would only be the cause of an even more intensified struggle that ended in the Revolution of 1910. The revolutionaries of the time after the revolution were a mixed bag, but thanks to people like Villa, Zapata or Cardenas many agrarian movements achieved huge gains in favor of the indigenous people. Today Mexico is still struggling against capital and US domination. We are a multinational country in which the majority at the very least are mestizos descended from indigenous people that were never exterminated by the spanish. Unlike the US where white people achieved ethnic hegemony thanks to genocide and slavery.
“Every island territory independent” should probably become an union/confederation.
