That makes no sense. I would stay in Iraq for spite after the bombing. Leaving only makes Al Qaida's actions successful. By backing down Spain is saying to Al Qaida "Hey, no fair you hit us we'll go back home now."
No one has the will to do the right thing anymore. Getting out of Iraq is one thing. But getting out of Iraq 2 days after someone does a terrorist attack against you only proves you are a bunch of cry baby cowards. I understand that party and it's voters doesn't want to be in Iraq which is a great POV and is to be lauded IMO, but to lay down for Al Qaida is insane.
