I’m no fan of Carter, I don’t trust evangelicals in general.
That said, Carter did not give away the Sinai, Begin did. Carter hosted and facilitated the Camp David meetings and accords, but he did not have to power to give away land that did not belong to the USDA or was not under its control.
Did he exert influence? Yes, but the decision in the ed was that of the Israeli and Egyptian governments and their respective leaders.
