Wasted Billions in Iraq!

I would like to know whose idea it was that when we go to war that we rebuild what was destroyed in the war!
While the United States is in a recession; people are losing their jobs, homes, way of life; and more people are going to the food banks now more than ever just to try to get by each month, the United States is wasting billions of our tax dollars over in Iraq rebuilding, and to make all things worse is that what we are rebuilding is not even being used! More than $5 billion dollars have been wasted in a country that we should not even be in. Why should we use our resources and tax dollars to force a country that is as old as Iraq to have the same views and laws that we have. Iraq was around before the United States was founded.
Now I'm not saying that I agree with the laws in  Iraq; but they are their own country and have their own leaders to rule the country as they all agree to.
But we go over and force them to accept our way of life and then we spend billions of dollars rebuilding for what? Empty prison that costed $40 million dollars, a childrens hospital that is unoccupied that cost $165 million dollars to build, and then we spend $100 million dollars for a waste water treatment system, but yet waste still runs in the streets.(The above information is from yahoo)http://news.yahoo.com/s/ap/20100829/ap_on_bi_ge/ml_iraq_us_reconstruction_legacy. While we are spending our tax money to rebuild Iraq our deficit has risen to $13 Trillion dollars and rising everyday. What would we do if the countries that we have borrowed from calls in our loans?
Just think of how many people in the United States could have been helped will all of that money.
People could still have homes, jobs and food if that money was spent here to help the people who was born in the United States.
It seems like we are getting fleeced and there is nothing we can do about it.
