Well I bet they can and should roll things back. Israel is an artificial state as you stated. So is Canada and the US. In Canada large blocks of land have been rolled back to indigenous Nations through court settlements and so they should to Palestinians, Africans, etc. Israelis should be happy with what they got in 48 or even just accept living in the Palestine they did prior to 48.That might all be true but that's the reality. The Palestinians need to live in reality not some fantasy about the right of return.
I'm not saying it's fair but it's reality. What the Palestinians should be doing is rising up against their own leaders who are not looking out for them and Hamas who use their own people as human shields.
It's a sad state of affairs but it's been going on since I was old enough to remember. As a child I sat with my father in 1972 watching the news coverage of the Munich Olympics when the Palestinian terrorist organization Black September took the Israeli hostages and ended with the death of 11.
I haven't known a time when the Israelis and Palestinians were not fighting. You can't blame the current administration or recent ones for this mess which goes all the way back to 1948.
And the ICJ is a branch of the United Nations which created this mess after WWII to begin with when they rolled out Measure 181 back in 1947.
Are you familiar with UNSCOP? The United Nations Special Committee on Palestine
Same thing happened on the African continent where they sliced and diced it all up in little pieces ignoring traditional ethnic lines and making a real mess of things which is why Africa has been consumed by civil wars for decades.
While I think the UN needs to exist the fact that both China and Russia are permanent members on the Security Council takes away from it's credibility.
I attended political conventions with my pops prior to 72. Nice
