"What If" while we fight war in Iraq to bring it to democracy, terrorists are fighting a war to:?

Destroy our Economy by draining our treasury, us fighting two wars, increasing our cost of fuel, cost of immigrant issues, making us defend our infrastructure, anything that increases our cost of living, doing business, and cost of living, putting our country in increasingly higher debt.

So terrorists just want to keep us fighting. They don't really want us to win, or lose, just drain our resources.

After all, isn't that how we defeated the Old Soviet Union, making the Cold War and Nuclear weapons too expensive to continue on?

So we are trying to win a Middle-East Military victory, But the bad guys just want to make life very expensive for us in every way.

How are they doing?
