Here's the curious thing. Per Zogby, only 40% of Americans think Bush is doing a good job in Iraq, yet 54% think he's doing a good job defendign the country against terrorism. According to another Harris poll, 62% of Americans agree with the statement that "Spending huge sums of money to invade and occupy Iraq has meant that a lot less money has been available to protect the United States against another terrorist attack". 59% agree that "Invading and occupying Iraq has motivated more Islamic terrorists to attack Americans and the United States". Only 39% agree that "Invading Iraq has helped to reduce the threat of another terrorist attack against the United States".
So the Iraq war is not going well. The war has diverted scarce resources away from fighting terrorism. The war has helped create more terrorists. Logically, then, invading Iraq hasn't reduced the threat of another terrorist attack. That makes sense.
I don't understand why people can believe these facts about the war in Iraq and still believe that Bush is doing a good job fighting terrorism. In Bush world, the war in Iraq is the central component to the fight against terrorism. If that's going badly, how can Bush be doing a good job?
