Without Iarael, there’d still be issues with Iran and Saudi, along with the conflicts arising between dictators and the people, as seen in Syria, Egypt, Libya etc.
I don’t think it’s a bad thing that Israel came to fruition, especially given the Christian and Islamic world’s persecution of such. If other states have an issue with it existing, I don’t think that can be blamed on Israel.
I admit that I do not know the ‘right answer’, but don’t think I can blame Jews for wanting their own state, especially when they migrated or were persecuted to go there.
