Actually, his claim was he advised Meir on the ‘67 War. Meir was not in the Israel government at the time, and Biden was an underclassman at Syracuse Law.
I met Biden and he personally told me while hard rock coal mining in Pennsylvania they tunneled to Area 51. The shaft came up in a room where there is a time machine that was being activated. The machine hurled him to Israel and Golda Meir was picked up on the way. They landed in a war room with Levi Eshkol and they negotiated the defeat of the Arabs. Well don’t be skeptical, it is as believable as his other BS stories.
