1. So he isn't giving the true reason, he's saying the typical "jew bad re: palestine" line from arabs, which he obviously doesn't care about or he wouldn't have gotten into bed with israel in the 1st place. So to me, it seems clear the reason he flipped was because the arabs gave him a better deal.

2. He claims the Americans & British are the ones who gave the jews weapons. Bullshit:

As a consequence of funds raised by Golda Meir which were donated by sympathisers in the United States, and Stalin's decision to support the Zionist cause, the Jewish representatives of Palestine were able to sign very important armament contracts in the East. Other Haganah agents recuperated stockpiles from the Second World War, which helped improve the army's equipment and logistics. Operation Balak allowed arms and other equipment to be transported for the first time by the end of March.

Operation Balak was a smuggling operation, during the founding of Israel in 1948, that purchased arms in Europe to avoid various embargoes and boycotts transferring them to the Yishuv.[1] Of particular note was the delivery of 23 Czechoslovakia-made Avia S-199 fighters.

"To most Israelis at that time, the recently lapsed British mandate in Palestine had been decidedly pro-Arab, and British Government policy was seen as anti-Zionist."

In the critical early stages, neither the UK nor the US supported the jews. Their key supporters were Stalin and the Czechs.
