Your video cites UN resolution 242 as one of the reasons. However, they cherry-picked one line out of the entire resolution as their justification for holding onto the West Bank. That is out of context with 242.
The purpose of that resolution was to tell Israel to get the fuck out of the West Bank. They have no sovereign title to that land. After 45 years, you would think you'd catch the clue no one is buying your rap.
Nice deflection. Israel will never make itself indefensible !
