Hi, have any of you read it?

I am interested in getting some clearity on something. In the book Osama makes a statement that I'm slightly confused by.

What I'm concerned with is in the chapter entitled "To the Allies of America, November 12 2002". The second paragraph, first sentence:

"What Bush- the pharaoh of the age - is doing, killing our sons in Iraq.."

What does Osama mean by "killing our sons of Iraq"? Is he refering to the UN sanctions imposed on Iraq, resulting in the deaths of hundreds of thousands of Iraqi children?

And second, what does Osama mean by "the pharaoh of our time"? I'm not much of a historian, so I'm a little confused at that reference. Why would Osama compare Bush to a pharaoh?
