I would never blame US for _not_ stopping the terrorists from
detonating a bomb. It's not their fault. Except that they
have provoked the terrorists to attack european countries
that have nothing to do with the conflicts.
But still, I would not blame them.

Well, this is also peculiar. If you'd never got into a fight with iraq and
such, nothing like this would never had happen. Instead you go poking around
your nose into other peoples asses, sniffing their business. If US had never
participated in any wars, but instead used all that money to help the
suffering
civilians and tried to make peace with peaceful ways, most probably nobody
would get hurt, and those boneheads would just kill eachother instead of
retaliating to bystanders just because they're so fed up with your monkeyass
politics.

Hmm, curious comparison.... but :
If you drive a car, you already take risks and put others into
risk aswell. If you do not follow the rules, the consequenses
are your fault. So, when you make the abrupt stop, you go and
explain why you did that, and settle things before they escalate.
I'd say doing that carstunt would be immature and would show that
you don't want to carry the responsibilities for your actions.
You just go and do it, and then blame everybody else.
