What does this cartoon mean?Dou you think America still practices imperialism?

I think this picture means that America thinks of them self's big and mightier than any other nation. I think this because the bald eagle is bigger and standing on top of America and all the other nation's symbols are very small. This picture is trying to say " We are bigger and better than any other country." I think this picture represents what they thought of in 1878 so that was then. What does the government think now? I think they still have the same idea that they are greater but a little less above their head.At the same time the eagle has a posture of protection. It's like if it's trying to protect the other nations. That posture is sort of true, because America would protect their allies.
I think America still practices imperialism because even though they are not powerful by land they are by money. People thought that the war with Iraq is about terrorism and land,(that's what i thought), but it's about oil. I really don't know why Bush would be in Egypt negotiating for oil if they are fighting for oil.I didn't think that America would be imperialism because they seemed very nice but since i entered fifth grade i have noticed more that America is imperialism, but they do that's what the war with Iraq is about. America doesn't practice imperialism that much with many nations but only with Iraq. I really don't think that a war for oil is a very good idea because we have other allied nations with oil.
