How it started: the Ottomans sided with the Nazis, so when they lost, the Ottomans also lost their land and the Allies got it, following the usual war rule where the winner wins the land. Dividing up the land is where the British Mandate for Palestine came from, under which we gave 2/3 of the land to the Arabs (Transjordan) and 1/3 of the land to Israel. But the Arabs refused to accept this and started the first of a series of wars against Israel. The Arabs, now also partially known as Palestinians, have continually refused to accept any peace deal, starting wars whenever possible and so far losing every one of them. Israel has repeatedly accepted peace deals, even at the cost of land, but it only works if both sides agree, which they don’t: the only deal the Arabs want is all the land and no Israel, which also means no Jews (proof: look at the Jewish communities within existing Arab states (TLDR: non-existent or shrinking)), which means the Arabs are hellbent on a genocide of all the Jews, and are determined to achieve that or die trying.
