In no way was the attack justified but we should check our expectations.

Kind of like sticking your hand inside a hornet's nest and expecting not to be stung.

To me that about sums up our decades-long involvement in political affairs in the middle east. Stiring up a hornet's nest for no good reason whatsoever.

We'd be much better served by minding our own business, let them blow each other to hell, and let God/Allah/Buddha/Yahweh sort 'em out.
