So what does that actually mean? There is NO place called 'Palestine' that is governed by 1 single, internationally recognized, entity. Do they mean 'Gaza' run by Hamas, an internationally recognized terrorist organization or do they mean Palestinian Authority's rule over the West Bank?
As for its 'right to defend itself' against Israel - who started this latest round of shit? 'Palestine' or the State of Israel.
What if Israel actually, formally, declared 'War' against this 'Palestine' and conquered it and decided to rule it in the same many as what the Allies did to Germany and/or Japan after WWII, then what? Would the rest of the world stfu? War's over, they wanted it, we formally declared it, conquered the territory, signed the formal ending of the war. Case closed.
