Yes, its true there were links between the IRA and Irgun. But thats a long time ago.
Sometimes I get the sense that Irish people are like, hey, we made peace with our enemies, why can't Israel?
As unreasonable as the parties on both sides of the conflict in the North could be, you can't compare for one iota the extreme ideologies held by too many Palestianians and Muslims in general. (which unfortunately has led to some Israelis holding extreme views as well)
Many Muslim countries don't actually recognise Israel as a country. (sorry for the wikipedia link but here https://en.wikipedia.org/wiki/International_recognition_of_Israel#:~:text=However%2C%20Egypt%2C%20Jordan%2C%20and,normalized%20bilateral%20ties%20with%20Israel. )
I for one would be very happy to see a 2 state solution, (in fact, Jordan was set up as a Palestinian state so it would be a 3 state solution) but it would require a huge mindset shift for this to happen. Israel withdrew from Gaza 20 years ago, instread of focussing on building a peaceful society, Hamas took all the money and aid and used it to build tunnels, buy weapons and rockets. They have been constantly aiming rockets at Southern Israel since then, culminating in the massacres on October 7th. Israeli citizens are terrified that a Palestinian state would just keep attacking Israel.
There are no easy answers.
Jews have nowhere to go. We have suffered just way to much persecution to feel safe in almost any country outside Israel. My family lived in Germany and Poland for 1000 years or more, it was a pretty good life until suddenly, it wasn't.
Its painful and actually ridiculous to be told that my grandparents who fled the Nazis and found a safe haven in Palestine in the 1930s were in fact colonisers.
