Not going to bother to look up the GDP per person in the West Bank and Gaza in those days, but in unadjusted for inflation currency, I'd guess triple what it is today. If I'm wrong, it's cause in double, their economy has only contracted by half.
Great idea, did a lot for the Arabs.
Solution will come about via compromise like all negotiations. Problem is, is that this word [compromise] does not exist in the Arab Muslim language, hence, no peace yet.
