I think the author of this article is mistaken about how the US approach has decreased terrorism. The US has invaded Afghanistan and Iraq and killed huge numbers of Innocent civilians. The logic being apparently (in Bush\'s words himself) 'We will make no distinction between the terrorists who committed these acts and those who harbour them.'
Lets assume that there is no hypocrisy involved and Bush actually means what he is saying here. If you do some basic research, you would quickly realize that the US is harboring terrorists in Florida right now. Jose Posada Carriles and Orlando Bosch killed 73 people when they bombed a Cuban airliner in the 1970\'s. One of them has been freed in the US and the other is being held by immigration authorities, while the US has refused to extradite him to Venezuela with whom they have an extradition treaty. So if you apply, Bush\'s logic, then the US should invade Florida and kill innocent citizens of the United States (just as they invaded Afghanistan). And this is just the tip of the iceberg. The US supports murderous regimes all over the globe. None of this has decreased the chances of terrorist attacks.
