Please read my editorial?! Any advice?

You have some good facts. The only thing I would suggest is adding a few more examples like maybe Afghanistan or Israel and Palestine -- both are very current, not that Iraq isn't but those two examples are more current than Iraq. Also watch your sentence structure (sorry I'm a journalist -- I can't help it), you have quite a few run on sentences and be careful not to get repetitive. In your first paragraph you stated America's invasion of Iraq was a case of imperialism twice, once at the beginning of the paragraph and again at the end. Other then that you make some good points and you support your statements well. Just one question -- for what subject is this for and what grade?
