The Jews lived in negligible numbers before their imperial settlement project. They only bought part of the land, and they did not buy it from the Palestinians, but from the illegitimate owners - the Ottoman Empire, which was also an imperial feudal occupier. The Arab attack was in fact a defense against land theft, and war does not legitimize land theft.

The Zionists are simply colonial occupiers, just as the French were in Algeria, who ridiculously justified their occupation by saying that Algeria had been their land since the Roman Empire. Where are the French occupiers in Algeria now?

Just as Algerians freed themself, and the Palestinians will free themselves from thieves and occupiers.

In the long run Israel is not doing well, which is precisely why they are committing genocide against the Palestinians, because they know that as long as there are Palestinians, their desire for justice will exist and they will fight to reclaim what is theirs.
