This is your
periodic reminder that the world is divided into "bombable" and "not-bombable" places. Bombing, for example, Paris, or anywhere in Western Europe for that matter, or North America, Australia, and a handful of other places, is an atrocity. Bombing places like Tehran is, well, maybe will elicit some statement of mild regret. But the decision to kill Iranians is seen as legitimate even while it may be a little distasteful.
The only way to make sense of this is as a kind of bigotry. Iranian lives are simply not worth as much as the lives of "first world" people.
