Israel and Palestine haven’t been at odds forever, they were at odds since WW1. There were long periods in time where people lived peacefully. There were religious tolerance laws going back to like 600AD. Christian pilgrims going there en masse. Treaties between Crusaders and Egypt allowing for religious freedoms. Almost 500 years of Ottoman rule, where anyone could practice any religion if they paid a tax. Communities had autonomy and could govern themselves according to their own laws - be it Christian, Jewish or Muslim. Said tax also exempt you from military service and was “proof” of allegiance to the state. Women, children, elders didn’t have to pay the tax at all. There were exceptions for basically anyone who couldn’t pay it - handicapped people for instance. If you were allowed to join the army, then when you did, the tax was waived with all the benefits still being given to you. Hell, some even were exempt for being too poor to pay it. The tax was cirqa 10 days of expenses of an average family. The richer you were, the tax went higher.

You also need to remember, that the population of Palestine was like 200k, with all the now huge cities having maybe 5k people in them in the 15th hundreds. 700k people in the early 20th century, when the Brits pulled a switcharoo and established a Jewish state. Any animosity from the past was long gone. The issues are because Jewish people were being resettled into Palestine in alarming numbers. Also, the literal decimation of palestinian population by the brits in 39’. Also the 700k people displaced in the Nakba. Also the further 400k displaced later. The genocide was happening in the 20th century. With people earlier living in a relatively free society. The formation of the state of Israel began with countries basically throwing a “hot potato” to Palestine, by genociding their own Jewish populations by sending them to Palestine. A one state solution was within reach, but it’s hard to do if you just draw straight lines on the map and call it a day.

As for the current day - Germany was the most horrific country during WW2 with countless warcrimes and mass killings, genocide of a few different cultures / countries, and the Holocaust. Now, after the war, Germany was welcomed back into Europe, rebuilt and is playing the first fiddle in the European Union, alongside France (and until recently the UK). If that can happen after Prussia, two World Wars, after Hitler, after the Holocaust, then a peace in Palestine is 100% possible.

What needs to happen is someone needs to kick Netanyahu in the balls really really hard. The government of Israel needs to change. The United States needs to stop its unconditional support of Israel - instead basing it on Israel and Palestine staying peaceful. And with time, wounds will heal. People will marry one another. Communities will blend together. And even if a single state solution is probably off the table in any way, shape or form, for at least a century, a two state solution is feasible.

The issue is, the US doesn’t need a peaceful Middle East. They need the “unsinkable aircraft carrier”. The US government doesn’t care that Palestine is disappearing and Israel is taking over. They might care that they antagonize Iran by bombing Iran. But at the end of the day, it’s just a statistic and “single issue vote” to many people, instead of the horrific reality. So until US voters see peace in the Middle East as an important issue, the genocide will continue.
