Why should we be in Iraq?

There are a lot of people who go either side on this topic; they either agree with us being in Iraq, or disagree with it.  I feel that we should be there.  Starting from the 9-11 attack, Afghanistan and Iraq have been a threat to our countries safety.  Us being there will keep safety to our country and stop anymore attacks, similar to the ones on 9-11.  Also, there are thousands of Iraqi citizens who are homeless and/or in danger for their life.  We are there helping those people, giving them help to find shelter and any other help they need.  Their own governments and armies are even ignoring this, and in some ways making it worse.  Their soldiers, in addition to trying to fight our soldiers, are trying to fight their own people too.  They hurt their own people and leave them in terrible conditions; living-wise and heath-wise.  These are just a few reasons of why i think we should be in Iraq as we are now.
