Perhaps I should have made myself clearer
The root cause is the failure to give the Palestinians a meaningful contiguous state of their own and allowing the creation and expansion of settlements on land that really belongs to the Palestinians
The Palestinian leadership especially in the West Bank is not immune they are corrupt and ineffective led by an near 80 year old, and it does not help that the suspicion is they have helped Israel capture and jail rivals like Marwan Barghouti it appears for a time that PA and Israel were quite comfortable with the status que
But the failure of having their own state cannot be largely blamed on Israel. They were offered a two state solution back in 1949, it was rejected and has since been offered multiple times. Not only was it rejected but those Palestinians that lived there at the time were told to leave by their Arab neighbours so that they could get 'rid of the jews'. The same Jews that were persecuted by the same Arab neighbours in countries they called home (Yemen, Morocco, all the countries that people come from that put an angry emoji when City say Happy New Year to the Jewish community).
Those jews made their way back to the land now known as Israel to make yet another home because they were persecuted just because of their religion. It is not in general a bidirectional issue (I accept there are extremists on both sides).
You are right, we can pick any point in time to make an argument, the point I wanted to make is it is a misconception that there were no Jews (or a small number) there since biblical times, holocaust happened, then there were Jews. Its just not true.
So I'd dispute your comment that it is Palestinian land because that statement also picks a point in time to argue. Personally i think a statement of 'equal' rights is fair but after years of trying to form a state for them, it is constantly rejected either by their governments who have squandered huge sums of money in aid, or in fighting between Hamas and Fatah, or by the Arab countries around them who simply don't want a Jewish state next door, or by unrealistic demands given no attempts have been made to iterate to a common solution.
Sure, perhaps that's not down to your average Palestinian but that does not imply it is Israel's fault either. Israel has since grown and each year that moves on, inevitably the practicalities of what can be offered is going to diminish as resources are constrained on the land mass. Don't get me wrong I'm against the settlements near Gaza but that land, even if given to them, will not solve the problem. People seem to think we are talking about huge country sized land masses. It is an area around twice the size of Manchester with a similar population. Being able to spill over into Stockport doesn't solve the problem.
Move forward 70 years and you have an area of land that was originally absolute waste land for the most part, now a very prosperous, westernised, place to live, Israel is being penalised for moving on. The irony is that Israel is one of the larger contributors to Palestinians than almost all of the neighbouring countries, this is despite the regular suicide bombings throughout the 80s and 90s, despite the 100s of rockets sent on a regular basis, despite regular attacks at the borders. Israel is incredibly restrained considering the constant attacks on their daily lives. Imagine if France battered Dover with rockets every single day? Or attempted to send suicide bombers to supermarkets weekly? Or came and took out the whole of the City end against Arsenal, killing all of the Junior pull throughs in front of their parents? That child that each of us sat next to, having their throat slit. Imagine enduring that for 70 years? These aren't hypotheticals, this is what has been happening against Israelis for 70 years.
What restraint would the British public expect, irrespective of how we have got to this situation in the first place? There is absolutely no justification and even the arguments around Palestinians being in poverty are fundamentally flawed because it is simply not Israels fault for the situation the Palastinians find themselves in today.
And it is not just Jews. Many Muslims contribute to the prosperity of Israel. Many muslims did stay in 1949 and they form part of the 20% of the population of Israel today, 20% who have representation in nearly all areas of the economic and legislative system, and who have also been protecting villages today from Hezbollah in the north. There are no special hospitals for Arab Israelis, no special taxis, no special buses, Arabic is taught in Israeli schools, signs are in both hebrew and Arabic, there is no segregation in restaurants, no special toilets. It is not perfect. There are social and economic gaps between Jewish and Arab Citizens but hardly an apartheid. There are even gaps between secular and ultra orthodox jews, nothing is perfect, we can draw similarities all over the world, even within the UK so why is Israel singled out?
I don't want there to be any doubt around my comments, of course all of the Palestinian children and younger generations do not deserve to have their homes blown to bits or be casualties of this war, it is incredibly upsetting but what alternative does Israel really have? Sit back? Let Hamas continue to grow? Yeah Israel was caught off guard but in part that is because they allowed Hamas to grow for too long and too busy focused on their own political infighting. If they went in and destroyed Hamas before then there would be uproar. Now this has happened there is still uproar that they go in heavy handed to destroy the infrastructure.
People seem to think Hamas' infrastructure is isolated to some 'Hamas building' that are easily dealt with away from civilians. It is just not reality, hamas deliberately put their infrastructure in schools, hospitals, apartment blocks, near key infrastructure, use their own people as shields. Israel for the most part does try to protect civilians (I'm sure there are incidents when this is not true) but it is incredibly difficult given the way Hamas is so intertwined in Gazan society. Again what does Israel do? Just let it go? Continue like this for another 100 years?
There is no real end because the time to have dealt with this (especially in Gaza) has now passed, populations have grown, resources outstripping demand. It is incredibly sad, a vicious cycle for next generations of Gazans but that does not make it Israel's fault.
