Usually we think of the victims of colonialism as the people whose lands were stolen and resources appropriated for the benefit of foreign rulers, not the people descended from the colonizers.
America has hundreds of military bases around the globe and exerts some degree of influence on practically every country on the planet. India occupies Kashmir, which it considers to be part of its own territory as part of a dispute that will likely not be resolved any time soon, and....that's it. And any history book will show that Indians are far more likely to be the victims of atrocities than the perpetrators, though of course there are some dark chapters in their story as well. So if we're expecting some type of fascist regime to rise up and take over the planet sometime in the near future, we probably shouldn't be looking to India.
