That is so true but we have given the majority back or they have been taken back .Indirectly we are responsible for the deaths of many in the millions and we do not celebrate.
So when do the indigenous people of North America get it back?
That's where the Brits fucked up, The Yanks eliminated close to 95 % of the people that occupied the US. I'm being sarcastic, before anyone gets their panties in a bunch. Oh and not so much given back, but rose up and took it back. (China, India, US, and Africa and middle east)
