You've got a good point there but limiting it just to the west shows your lack of understanding about world politics. The imperialist approach is present in many parts of the world and throughout old and recent history. Besides the west, Russia (warning: propagandists incoming) is doing that with neighboring countries and in Africa, just like China and other African countries are doing that too in Africa. Rwanda in Congo for example. China to Hong Kong and Taiwan. Japan and their massacres during WWII. Morocco in the Sahara region. Israel in Palestine, and vice versa Hamas to Israel. In Islamic countries: sunnies vs sjiets (or however it's written).

So your point of view is a bit too brainwashed around the west I'm afraid. Lots of governments trying to subjugate other countries for wealth and power benefits.
