Dying for your cause

This Islamic cleric gave a speech recently where he argued that dying for your cause is just.

In November 2004, Dr Tamimi told the BBC that he was prepared to be a suicide bomber if the opportunity arose. In an interview which was roundly condemned, he said that 2sacrificing myself for Palestine was a noble cause. It is the straight way to pleasing my God and I would do it if I had the opportunity".

I agree. Dying for your cause can be just. However, the part about having 50 innocent civilians dying with you in a pizza parlor is the part that troubles me.
Perhaps to these guys any western, civilians, military, everyone is the enemy. If that is so, how come we don't treat their civilians as the enemy either? Instead we cry and complain when a civilian in Lebanon cuts his finger.

I heard one leftist a few years ago argue this:

It was just for Osama to bomb the world trade center because as a democracy, U.S. citizens all had a stake in what the U.S. goverment was doing and therefore were liable for the crimes of the government. In contrast, Iraqi civilians were innocent because they were unable to affect the decision making of Saddam Hussein. Therefore it was criminal to target the Iraqi civilians.

Yet, at the same time, Osama claims that he is fighting for the people. With rationalization like this how is it possible to reason with the left (where everything is fake but accruate).

We do it to ourselves. More from the article about the Islamic cleric above:

Dr Tamimi, a prominent member of the Stop The War coalition, is married with three children and lives in Willesden, North West London. After coming to Britain from the Middle East more than 30 years ago, he and his family have become British citizens and live in a council block.

What a joke. Who let this guy into Britain.
