I think this only goes out to show that criticism towards Israel waging warfare is not really about the way that warfare is fought, but really on the right of Israel to fight at all. As no one in history has achieved a more precise attack in urban setting towards a non-uniformed organization ever.
You are making that up and quoting yourself. There was not a single fire-control system onboard these pagers; there was no visual designation of the target, and no confirmation that it was being carried by it's owners. The target was broadly designated and not even discriminated on a case-by-case basis. A button was pressed, and consequences including the death of a child are now in play.
Israel has the capability to field targeted strikes on their own using domestic Litening and SPICE munitions (not to say they don't end up targeting civilians anyways). The unforunate bottom line is that this was an indiscriminate and presumptive attack that generally relies on a complete disregard for collateral damage. Innocent bystanders died, ones that would not be targeted by any morally accountable soldier in the command-and-control loop. That means an error was made, in civilized armies.
International law allows, to some extent, collateral damage during war (and Israel and Hezbollah are certainly at war). What percentage of collateral damage would you say is acceptable here? 50%? 20%? None?
Just as footnote, I think that mutilated is the correct word here. Having in mind that 2000 people lost fingers, or noses or a chunk of their hips.
If an enemy had exploded small remote controlled bombs in American supermarkets and homes targeting members of the American political parties, the sponsors of terrorism and oppressive dictatorships in many foreign countries, there is no question we would characterize it as a terrorist attack.
In your metaphorical scenario in America does the following also hold for the said American political party:
* It has a parallel illegal army that is stronger than the US army
* It started a war attacking a neighbor using rockets, mainly attacking the enemy civilian population
* It is controlled by a foreign government
* Its attacked members are in active combat roles inside the united states
* It is part of the US government yet the government refuses to disarm it or take responsibility of its actions
