Gee. The US spent most of the 20th C invading countries, mostly for 'violating its dogma' - for being too democratic, for not being subservient enough, in the service of US business interests, mainly. Supporting dictators, giving a lot of weapons, training torturers, subverting democracy, assisting/staging coups, etc etc from Guatemala to Iran. It's a long and well-known story.[0] Millions died.
