If peace was worth $2 billion per year in the 1970s, they might reason, what would it be worth in the 2010s? $20 billion? Younger, more energetic Egyptian politicians with less to lose might have some strong opinions on this subject.
But how could the Egyptians intimidate Israel? Perhaps they could co-opt the Jewish State. After all, if Egypt were to demand an order of magnitude cost of living adjustment up to $20 billion, then it would only be right and fitting for Israel to get $30 billion from the U.S. taxpayers.
