"You agree that the Arabs have no right to the area, since they took it force"

I don't think that they did. The converted much of the existing population, albeit some by force. The descendants of those conquered people have the best claim to the land.

While Bruce is correct that there were SOME Jews in Palestine before the Zionist movement started resettling, the vast majority of the present Jewish population are immigrants and their descendants.

As far as "the right of conquest" BB speaks of. Israel's current leadership still has blood on its hands for the lands they took and the UN Mandate has been invalidated because only the provisions convenient to Israel have been upheld. Witness the blockade of Gaza, and the military occupation of the West Bank of the Jordan.
