Ah, now the monkey comes out of the sleeve, as the Dutch say.
You justify the colonization of Palestine on "might makes right." By that metric, anything that the Palestinians do to Israel can be justified after the fact with a simple "The Israelis lost [insert name of war] to [insert name of Palestine-aligned victors] and thus LOST control over their land. End of Story."
What I say is that no outside power has the right to take land from indigenous people by force. It has happened since humans have been around, but that doesn't make it right.
Prior to the British Empire colonizing Palestine the Jews, Arabs, Christians and atheists in the area lived in relative peace amongst themselves. That is what they should have again.
That is what I have to say.
