You're just showing you don't understand basic concepts. You called China's liberation of Tibet "colonialism", proving you don't know the meaning of it. Expansionism isn't "when borders grow at any time in history", it's a tendency of a nation to view its territorial expansion as a desirable goal for the sake of it or for access to resource for example. Austria building an embassy in Tibet would grow Austria's borders, technically counting as expansionism according to you. You have lib level of politics knowledge and analysis, and it's hysterical how you try to bend definitions to make things look good for US imperialism
