GOP, you believe what?

While there were many things to take away from the CPAC convention, the one that really struck me was the fact that a majority of the people there believes that the Iraq war, started under false pretenses by the George W.Bush administration, was the right thing to do and worth it. Now, while I can easily argue whether it was the right thing to do, I can understand those on the other side. But was it worth it? I don't see how anyone outside those who simply wanted Saddam gone could believe that. I'm not talking about the over 3,000 troops that it cost this country, although that is a tragedy in itself. I'm talking about whether we could literally afford it. At a time where the country is over 16 trillion dollars in debt, imagine if that was 1 to 3 trillion less. Yes, that was the cost of the Iraqi war, depending on the source and how many spent (The Washington Post had the high number, and it is not a liberal paper at all) and it is still growing. Can anyone believe that this action was really worth 6% to 18% of our deficit?
I can believe that the GOP can believe a lot of things now. But GOP you believe what about the Iraqi war?
