I have to disagree with Obo. If the Yanks invade a country they call it intervention, but if they saw the Soviets do it the Yanks called it invasion. If the Russians moved into a country it became a subservient state of the USSR, true. But if America move into a country, even today, it becomes a subservient country of the USA, with US military bases, MacDonald's branches, US oil companies, banks, ect. while it's people remain poor. Soviet occupation, American occupation, what's the difference?
