Not only do they not care, they probably see it as a potential propaganda win. If some settlers die in the bombings, they can blame it on the Palestinians for taking them in the first place (if not just outright say they were executed). Any settlers that survive will be seen as a victory.
Palestine
A community for everything related to Palestine and the occupation currently underway by the occupying force known as Israel.
Anti-Zionism is not anti-Semitism. Existence is resistance for Palestinians.
Please refer to Israel as Occupied Palestine, or occupied territories. The IDF is a fascist and ethnonationalist occupying force. Israelis are settlers. We understand however that the imperial narrative (which tries to legitimise Israel) is internalised in the imperial core and slip-ups are naturally expected.
We always take the sides of Palestine and Palestinians and are unapologetic about it. Israel is an occupying power whose "defence force"'s (note the contradiction) sole purpose for existing is to push Palestinians out so they can resettle their rightful land. If you have anything positive to say about Israel we do not care.
Why detain citizens in the first place?
Because the Zionist régime has backed the Palestinians into a corner. The Zionist rulers don’t want to talk, they don’t want to return Palestinian land, they don’t want to raise Palestinian living standards or upgrade them to first‐class citizens, so the Palestinians don’t have any options left but to (figuratively as well as literally) throw whatever they can to get out of the corner. They are desperate. The Zionists are not.
It’s an awful situation, but the Zionist rulers were the ones who set the stage for it, and if you ask me, they’re merely reaping what they’ve sown.
