It had to be a mistake. After all Spain supposedly bought off the terrorists by electing Zapatero.
The shock comes from the premeditation. Spain expected to lose a few thousand people and various infrastructure by accidental bombing and suicide-oopsies. Being as to how this attack was deliberate, they are faced with unsurmountable obstacles in overlooking it.
I feel bad for the soldiers (obviously).
Can’t help but think that Spain’s shameful premature withdrawl in Iraq encouraged this type of attack.
The Arabs will again demand “Al Andalus”..
