People are criticising Israel for murdering people, for land grabbing and displacement of a people. If you actually listen to ordinary Palestinians it is not that they want to necessarily dismantle Israel but they want the land grabbing, the occupations, the bombings to stop. Palestinians have been constantly under attack since 1948.
You and others have talked about pro Palestine supporters wanting to dismantle Israel but that is not the case. Even those that have expressed a desire for a one state solution say that they envision a country where the people from both countries can stay but have equal rights and be equally represented in the police, army, government etc…
If you look at maps of Palestine and Israel it is Israel and not Palestine that is constantly expanding territory, displacing neighbours and taking land. Many in the current government talk about Greater Israel, an idea that would see the West Bank, Gaza and parts of other neighbouring countries become part of Israel. You can’t say you fear being erased as you erase the other group and openly discuss completely erasing them.
As an Irish person I can understand the desire for one country - I’d love Ireland to be reunited, Northern Ireland is a little older than Israel at just over 100 years old and it’s partition also brought about war and conflict, it created segregation and an unequal society where the indigenous Irish catholics had less rights than protestants who came to Ireland during plantations (over 100’s of years so pretty Irish now). I’d love to see a united Ireland where everyone stays and is represented - interestingly my British unionist friend from Northern Ireland has discussed how she would like one country too but would like it to be part of the UK whereas I would like it to be part of Europe. Both of us are happy with the current situation though as living in harmony with equal rights is the goal. We can have these conversations without talking about erasing each other - we can all have equal rights and retain our unique identities.
Northern Ireland got peace not through the years of bombing and fighting but through talking and through compromise. The IRA never attained their goal of reuniting Ireland but the catholics got equal representation in the police, in the army - at all levels across the board. They are now more or less equally represented in government too. People in Northern Ireland have the right to identify as British or Irish or both, they can have both passports if they wish. They can live in any area, work in any job they are qualified for. There is still some sectarian violence particularly among disaffected teens but the IRA, UVF etc have largely gone, the bombings have stopped. There are no longer soldiers with large guns patrolling streets.
I believe if Israel stop expanding, renounce all plans to expand further, give back the land they have taken in recent years - that will go a huge way to ending Hamas. If people are able to live their lives in peace, have freedom of movement, equal rights, no roads that are just for one group etc… they won’t join terrorist organisations (as seen in Northern Ireland). Give Palestinians equal rights to walk the same roads, live where they want, buy land without the fear of it being taken away!
