I guess I shouldn't let the second anniversary of September 11th go by without passing comment, except that I've got nothing much to say about it.

Two years on, the War on Terror that the attack on the Twin Towers prompted is foundering. Yes, two regimes have been toppled, a number of key al-Qaeda figures have been arrested or killed, co-operation between countries has improved and the terrorist networks have been disrupted.

But the attacks are continuing -- perpetrated by a range of splinter groups scattered around the world. Osama's still out there somewhere (tending his sheep by the looks of the latest video) and Iraq is in chaos.

The world seems more dangerous now than it did two years ago.
