They feel that the reason the country has not been attacked since 9/11 is because they are killing the same terrorists in both places that might otherwise be attempting to find their way to the U.S. Most would agree that a direct attack on terrorism was not the initial reason for going into Iraq in 2003, but it took a little less than three weeks for us to see religious extremists there.
It's a long read, sorry about that, but I think you need to take the time to read the whole thing.
