What's the price for you to call for killing *any* foreigner no matter how unjustified? About zero. Sure is easy to dehumanize others and enjoy the powerful feeling. The arrogance of power...
(I'm not saying how justified this attack was, it's a more general commebt about how easy it is for the citizens of the powerful nation to say 'good' to unjust killing).
You say in the first sentence you're not stating your opinion on the justification of the attack, and then you call it unjust in the very next sentence!
