But presidents matter. That's one of the biggest lessons I learned being in the White House.

In every single case, the truth is that the atmosphere created by the Iraq invasion and the staggeringly mismanaged occupation has incited terrorists to act. It's been a contributing factor. It's unavoidable throughout Europe - in Spain, in Germany, in Britain. The truth is that we need long-term American policy to shift in order to really soak up and get rid of these sources of terrorism that threaten our Western allies.

It was an absurd theory that by cutting taxes you would increase government revenues, because the growth of the economy would create an overflow of taxes that would fall into the government coffers.

The Bush Administration, and particularly Bush's chief political strategist and Deputy Chief of Staff, Karl Rove, have been expert in both galvanizing and mobilizing the fears and resentments of people. A good part of their politics consists of being against others who are defined in stereotypical terms. These others don't, in actual reality, exist. The so-called Democratic elitists, for example, are a stereotype who they can hate. Anyone who watches Fox News or listens to Rush Limbaugh knows that this hatred of the other is at the core of their politics.

Bill Clinton was in the line of great progressive presidents who faced the realities in his own time and applied innovative solutions to problems.

The attack on Clinton on terrorism is entirely politically inspired by the right-wing of the Republicans, and has no basis in fact whatsoever.

Who was it in Afghanistan who screwed up in Tora Bora and let bin Laden escape? It was the Bush Administration. Who leached all the resources, military and civil, from Afghanistan, creating the instability that we see there today in order to prepare for the misbegotten invasion of Iraq? It was the Bush administration. If there's a terrorist problem today, who is responsible now? Bush has not done the job.
