Do you think the US is/has been imperialistic?

I think that the United States can be perceived as being imperialistic. I mean when you look at the war with Iraq we see some imperialistic tendencies arise. I mean at first our purpose was to fight because they ran a terroristic attack on us. I don't think our purpose was to take over there land, but does it appear like that ? I mean were have been at war for over nine years, what was the true purpose. I mean incident people are dieing each and everyday to protect our country.

Pros:

1.The Third World Countries have most of the factories.
2.Our government is modernizing.
3.We are feared by other countries which shows that we can be courage.

Cons:

1. We look at how efficent our country is rather than trying to conquer and take over other ones.

2. We make it clear that we do not want to become communist we run on capitalism.

3. We act based on one decison rather then what is benefical to our country.
