What is happening in Jerusalem?

^ There was not just one method: some Palestinians sold their lands, some were chased away, others were killed...

...and some were told by neighbouring countries: come stay with us for a while until we settle this problem.

Back in the 90s, when Biden felt less compelled to act nice, he said openly in the Senate that supporting Israel was a matter of American self interest and it would invest money to create an Israel if it had to.  Can't find the clip of it now; if I can, will post it. 

I would agree were it not for the virulent anti Semitism which was most pronounced in Nazi Germany but generally widespread in Europe during that period.  It created an imperative for a 'safe space' for Jews because they could not be safe in Europe.  Had anti Semitism been tackled head on, much trouble would have been avoided (well duh) and one of the incidental by products would have been the non-creation of the Israel-Palestinian dispute.

Well, the reason any discussion on Israel-Palestine gets into blame game because the mess was an intractable one from inception.  The last two statements you mentioned would appear to be valid from a purely Israeli or Palestinian perspective.  Palestinians would regard Israelis as encroachers. Being directly affected by the creation of Israel, they would be less inclined to look at the historical context.  Likewise, because Israel itself is so crucial for Israelis, they too would be less inclined to put themselves in the shoes of Palestinians and act on the threat faced from terrorist operators engaged by Palestine.  And it's absolutely true that they did and not just today.  Even back in the day, Arafat helped the Ayatollah revolution.  So Israel's suspicions aren't unfounded. It sounds extremely depressing to say so but the problem is now a Gordian's knot.  Any possible amicable solutions could have been arrived at in times when more peace-inclined, moderate forces were in power. It's very unlikely to be solved NOW.  The xenophobia of Brexit undid the delicate soft border arrangement that brought peace to Ireland. If that could not survive the return of far right forces, what chance does the Israel-Palestine dispute have?

If the mess you are referring to is the Israeli-Palestinian Arab conflict generally, then I disagree. The fault lies squarely on Jews and Arabs. Whatever side you take, the mess exists because Jews and Arabs don't agree on what to do and how to do it (spoiler alert: I obviously put the majority of the blame squarely on the Arabs but that's not my point in this particular post). 

Sure Western powers have interfered out of their own interest. And Jews and Arabs have also leveraged their diplomatic ties and abilities to varying degrees of success to enlist Western assistance. But at worst, this exacerbated the conflict, it did not create it.
