Would you let them keep doing it while insisting that reprisals are off limits?

Yes

Nice of you to value their citizens’ lives above your own. I doubt that will be much of a consolation for your countrymen that you’re willing to sacrifice to violence. Expect more human shields in the future now that you’ve proven the tactic so effective.

What kind of question is that?

A moral dilemma.

If you answer no to that you’re saying I’m no better than them, and if you’re ok with that then what is your moral high ground here?

If you answered no to that I’d say you’re honestly assessing the grim realities of war, where the goal is to pacify the enemy without sacrificing your own people, even if that may result in collateral damage.
