Point to another place to setup a secure garrison in the open air concentration camp that is gaza. I’ll wait. Similarly it’s not justification because it isn’t justifiable, as I said it’s still shitty to do but it’s easy to see why it was done. That said you should look into operation shark that was aimed at the proto Israeli terror group Lehi for the bombing of a civilian hotel that contained the Palestinian embassy in 1946. Would you like to venture a guess as to where they found insurgents and weapons? Here’s a hint: chools and opitals.

Correct, you can’t answer because it will destroy your argument. You would do it, I would do it, any person with a brain would which is why there are specific rules about it in international law and it isn’t because it never happens I can assure you of that, quite the opposite in fact.

the action of showing something to be right or reasonable. It isn’t right, nor is it particularly reasonable so it isn’t a justification. You could make a hundred legit arguments here but understanding=justification is hilariously stupid.
