Isn’t that a war crime? Now, our weapons are probably accurate enough to get them anyway, unless they store them in hospitals and such, but it doesn’t negate the intent of the Iranians.
It seems the other side is playing on fears of civilian attacks, e.g. if Israel attacks the installation and in the process kills civilians, it gives Iran the green light for its own attacks on Israeli civilians. Russia recently attacked a civilian installation in Syria, possibly to show that they have no qualms about it.
A game of provocation using civilian lives, and all this with the possibility that Sadam’s WMD are stored underground in Damascus.
