The Power of Nightmares - Part I
Baby It’s Cold Outside”
In the past our politicians offered us dreams of a better world. Now they promise to protect us from nightmares.
The most frightening of these is the threat of an international terror network. But just as the dreams were not true, neither are these nightmares.

Part two, the Phantom Victory looks at how two groups, radical Islamists and neo-conservatives with seemingly opposing ideologies came together to defeat a common enemy.
Among the many foreigners drawn to Afghanistan was a young, wealthy Saudi called Osama Bin Laden.
