Sep 11: 3,000 dead in an event that was without doubt a massive tragedy. However, it was not the first terrorist atrocity and arguably an aberration waiting to happen, more to do with lax airport and airline security. The world was arguably a more dangeous place in the 70s with the threat from Palestininan and Communist inspired terrorism.
Iraq - never a threat to the UK or US unless you are insane enough to believe Mr Blair. Until now, that is, now that we have put ourselves in harm's way....
Libya - what nuclear profile was lowered? Gadaffi giving away something he never had, in a cunning move.
Iran - the nuclear profile is down, then up, then down. Also, with over 100,000 troops tied down in Iraq, the Iranians know that threats are empty rhetoric.
Most of the changes are down to a lack of Western vigilance and an excess of Wester vigilante behaviour!
