And yet, most in the West still don't get it

Speaking to an invited audience of military commanders and academics on board a warship in Plymouth, the Prime Minister [Tony Blair] disclosed his fears that the West no longer had the stomach for sustained military campaigns. He also appeared to blame the media for the global outrage provoked by the war in Iraq.

"[Islamic terrorists] have realised two things: the power of terrorism to cause chaos, hinder and displace political progress especially through suicide missions; and the reluctance of Western opinion to countenance long campaigns, especially when the account it receives is via a modern media driven by the impact of pictures.

"They now know that if a suicide bomber kills 100 completely innocent people in Baghdad, in defiance of the wishes of the majority of Iraqis who voted for a non-sectarian government, then the image presented to a Western public is as likely to be, more likely to be, one of a failed Western policy, not another outrage against democracy."

Acknowledging the public backlash against the Iraq war, Mr Blair said: "Public opinion will be divided, feel that the cost is too great, the campaign too long, and be unnerved by the absence of 'victory' in the normal way they would reckon it.

But the Prime Minister added: "They will be constantly bombarded by the propaganda of the enemy, often quite sympathetically treated by their own media, to the effect that it's really all 'our', that is the West's fault. That, in turn, impacts on the feelings of our armed forces. They want public opinion not just behind them but behind their mission."

He warned that the terrorists had learnt how to use the media to undermine public opinion. He cited a website, called LiveLeak, showing "gruesome images" of the "reality of war" as the kind of propaganda weapon that was being used by international terrorism.
