If it were only just about religion, I could wholeheartedly agree with you. But it isn't just that, or even that.
After centuries of relentless persecution, culminating in the Holocaust, and in the face of continuing - if lower-key - antisemitism worldwide, the people of Israel hoped they had somewhere they could finally feel safe. Safe in a way no diaspora Jew has ever been able to. It has turned out not to be the case, which has made them angry. But now, for the first time in centuries, they are in a position to fight back.
The Palestinians have been forced off their ancestral lands by foreign invaders. They are crammed together in what amounts to Ghettoes, where poverty and lack of hope breed resentment.
When two people, or peoples, both believe they are the sole rightful owners of the same thing, there can be no reasoning, no pragmatic solution, not even a meaningful discussion. Only simmering resentment, paranoia and conflict. With those, come leaders whose grip on power relies on feeding those feelings. England and France were at war for a hundred years because both sides believed they had a right to the French crown. It took a change of dynasty in the UK to change that. The problem of Ulster comes from similar roots and is still a running sore in UK politics.
Even if every Palestinian converted to Judasim, or every Jew in Israel became a Muslim, the conflict would continue because it is about the land, not religion. Until and unless one side or the other decides voluntarily to give up their claim to the land of Palestine, the conflict will continue. Does anyone honestly see that happening?
