"I Go Undercover in Palestinian Cities" | The Ask Project

This is Corey, the guy who does this project where he asks random Israelis and Palestinians questions, being interviewed. I highly recommend his channel to anyone who wants a better understanding of the conflict. He's not taking sides and he asks difficult questions (coming from his viewers) about the conflict to both. If you pursue this you will certainly find out how much you do not know about this conflict.

To some of your other points since I'm revisiting:

- There are dead children because Gaza is extremely dense and half the population are children. That said the blank statement is not useful because the Palestinians counts are iffy, one example is that they include combatants who are under 18yo, and it deflects blame from Hamas from operating under the cover of children and not providing for their safety. This is not to say we should not feel sorry for dead children. Most critics of Israel are unable to offer an alternative way for Israel to defend its citizens given the specific circumstances. If Israel had a magic weapon that only killed Hamas militants I'm sure they'd use it. If you're asking Israel to send soldiers into an urban environment to ensure no uninvolved are killed instead of dropping a bomb on the enemy, I'd say, within reason, go with the bomb. That's what any military would do, what the US and its allies did against ISIS and in other places. That's how wars are fought. Nobody puts their own soldiers lives at risk to protect civilians the other side puts at risk by their actions.

- The argument that Palestinians didn't get to vote since 2006 is also pretty weak. One reason they didn't get to vote is that the PA didn't hold a vote because Hamas would win. Polls show broad support for Hamas amongst Palestinians. Either way, they are the government of Gaza whether they enjoy support or do not. When non-democratic countries go to war their citizens suffer consequences whether they got to elect their government or not. We should feel for the unfathomable numbers of young Russians that have died in Putin's crazy war on Ukraine. Does that mean that Ukraine should surrender because those Russians didn't vote for Putin in a free and democratic elections? No.

- Israel has to, under international law, ask civilians to evacuate and indeed facilitate their evacuation from combat areas. That's exactly what it did. Now the West attacks Israel for doing exactly that. I would say there's nothing Israel can do that's right. If you can suggest a reasonable path for Israel to protect its citizens from Hamas and earn the support of the critics I'm all ears.

- I'd love for there to be a way for Israel to de-escalate the conflict. I lived in Israel during the suicide attack campaign that Hamas waged on Israel as Israel was trying to make peace with the Palestinians and get to a two state solution (circa 2000). The failure of that process and the failure of Israel's withdrawal from Gaza proves there is no partner for any sort of de-escalation. Again, go check out some of those videos. The escalation came from the Palestinians (and Iran) and Israel has no practical way to de-escalate.

I also grew up in Israel at a time where Palestinians from the West Bank and Gaza had complete freedom of movement in and out of Israel. Israelis shopped in the west bank and Gaza. Palestinians worked in Israel. There were essentially zero settlements and zero settlers. The PLO (backed by the surrounding Arab countries) murdered Israeli civilians left right and center. Not because of the settlements, not because of road blocks, not because of settlers attacking Palestinians. Just because Israel exists. The Palestine they want to liberate is and has been all of Israel. This is not about the individual freedoms of the individual Palestinian and how Israel "oppresses" them. A by the way is that when Israel took Gaza from Egypt in the 6-day war many Gazans were extremely happy to not be under Egyptian rule. The Egyptian and Jordanians, prior to 1967, didn't consider for a microsecond giving the Palestinians their own country over those areas that they controlled. But both are happy to ask Israel to do that now.
