The Jewish people began by buying the land legally in the late 1800s as a way to escape persecution.

This is completely ignoring the boycott and parallel society angle. What Zionists did in pre-mandate Palestine was also forced expulsion of Palestinians; the forcing part was simply delegated to the state. Had they simply wanted to settle in Palestine nobody would've minded, but that was fundamentally not what the Zionist project was.

According to Israeli historian Benny Morris, Zionism was inherently expansionist and always had the goal of turning the entirety of Palestine into a Jewish state. In addition, Morris describes the Zionists as intent on politically and physically dispossessing the Arabs.

The World Zionist Organization established the Jewish National Fund (JNF) in 1901, with the stated goal "to redeem the land of Palestine as the inalienable possession of the Jewish people." The notion of land "redemption" entailed that the land could not be sold and could not be leased to a non-Jew nor should the land be worked by Arabs.[145] The land purchased was primarily from absentee landlords, and upon purchase of the land, the tenant farmers who traditionally had rights of usufruct were often expelled.

Nazis had nothing to do with the Jewish people establishing a homeland in Palestine.

Nazism had a lot to do with the German people expanding their homeland to Eastern Europe and Russia and murdering the inhabitants. Starting to see the similarities now? Nazism and Zionism are sister ideologies, both fruits from the same rotten tree that is European settler colonialism.

As someone who has to deal with real people at demonstrations regularly, these horrible genocidal sentiments are not just limited to internet trolls unfortunately.

Also as much as they are detached from the general population, all the politicians and Israel lobbyists and MIC lobbyists still are real people too.

I think Israel is foolish. They are protected by their international support and not viable on their own. Trump is unpredictable and nationalistic.

That’s weird logic. If we’re going with Trump being unpredictable, then it really doesn’t matter what Israel does in terms of maintaining support from Trump.

And countries don’t base foreign policy based on what teenagers on the internet want. They base it on interests. What has Israel done that goes against anyone’s national interests? Iran is a thorn in everyone’s side, and Hezbollah has been weakened and cut off from easy supply from Iran because Assad’s regime is gone. It’s not in anyone’s interest for Iran to have nuclear weapons, and Israel has proven their capability in taking out Iran’s air defenses. The Houthis are a problem for global trade and Trump isn’t going to hit them as long as they keep to their deal and not hit US shipping.

So given everyone’s interests most countries might wag their finger at Israel publicly for political reasons, but people in power know that if their people were taken hostage by terrorists, they’d do much the same thing as Israel has done. The US has become unreliable in dealing with the middle east (not really caring about Houthis attacking other country’s shipping) so they need an ally in the region to keep Iran and their proxies in check. And Israel has demonstrated a lot of capability in that regard. So do you think countries are going to isolate Israel for the sake of a small group of protesters constantly shouting insane slogans?

Resolution 242: On November 22, 1967, the UN Security Council unanimously adopted Resolution 242

• The “inadmissibility of the acquisition of territory by war.”

• The need for Israeli withdrawal from territories occupied during the conflict.

They attacked on a Monday, knowing that on Wednesday the Egyptian vice-president would arrive in Washington to talk about re-opening the Strait of Tiran. We might not have succeeded in getting Egypt to reopen the strait, but it was a real possibility.” -  Dean Rusk, the Secretary of State of that time

“The Egyptian Army concentrations in the Sinai approaches do not prove that Nasser was really about to attack us. We must be honest with ourselves. We decided to attack him.” -  Menachem Begin

So there was no eminent security risk, the attack was not proportional and Israel kept the west bank and east Jerusalem violating the need for Israeli withdrawal from territories occupied during the conflict
