Iraq – In 60 Years

I was talking to my father, who noted… people are saying: “We’ll be in Iraq a long time. But we’ve had bases in Germany for 60 years, and in South Korea for 50 years. It will be no different.”

But why do we have bases in Germany? And why do we have bases in South Korea? Twenty years ago maybe it made sense, but now? And what exactly will be the purpose of US forces in Iraq in 60 years?
