Why did the US invade Iraq in 2003?, research paper help

The
Research Paper. 

You will write a 5-6page ORIGINAL, ANALYTICAL research
paper.  In this paper, you will
choose an event from the last 100 years that addresses a why question, or which
seeks to explain an outcome of some significance over the last 100 years.  The paper must be based on at least 3-5 primary
sources that offer insight into the question; three scholarly books and four
scholarly articles.  The research
question and argument must be laid out clearly and  should give a
sense of how you will prove your argument.

The topic question is “Why did the US invade Iraq in
2003?”

You should organize your paper in:

1.  a clear
introduction that presents the puzzling event/issue that you will explain and
states your argument in brief;

2.  supporting
sections with evidence that develops your argument and considers alternative
explanations, and;

3.  a
conclusion that summarizes your arguments and illustrates its significance
(answering the “so-what” question). 

All papers must be typed, in 12
point type, New Times Roman font, double spaced, MINIMUM MARGINS OF 1 INCH
ON ALL SIDES.  All writing assignments
should have an argument put forward by you. 
Ideally, they should address a “why” question and have a thesis statement
(an argument that answers why something happened for example). 

Be very careful about writing a paper that simply
summarizes the contents of the primary sources. 
Of course, you will have to understand the documents and briefly present
an overview of them, but your assignment is to explain and interpret
the evidence (documents).  Additionally,
beware of gushing or ranting about your documents. Don’t simply assert or
suggest your views. Instead, prove and demonstrate them.
