"Relatively little. "
Thanks. It's a little hard to believe, but I appreciate the information.
It became a cold war issue post 67, and particularly into the 70s. And of course after "peace" with Egypt, an obligation to maintain Israeli military superiority in recognition of the tactical disadvantage of returning the Sinai. For the second time. The first time around Eisenhower pledged to maintain Israel's free access to the Red Sea through the Straits of Tiran. LBJ reniged on that pledge when Egypt expelled the UN force from the Sinai, began moving in troops, and blockaded the Straits in May, 1967, leading to the 1967 war. One can only speculate what would have happened had LBJ and the UN stood up to Egypt.
