#1. The Nazi Germans could have easily reached Palestine and killed the Zionist movement once for all. Why would the Jews take such a chance?
#2. There was no guaruntee the entire Ottoman Empire would collapse. The Ottomans were allowing the Jews to move into Palestine at a steady pace. Why would the Jews mess with such a favorable situation?
The whole idea that "the Jews" are responsible for BOTH WW1 and WW2 is just pathetic and stupid.
