This poll ias based on the perecption of Israeli politicians by Israelis. I bet if Israeli Jews were to be honest about their politicos--Isarewl would be topping the list of most corrupt. Most of Israel,s politicians approve of the occupation---the theft of land---assassinations---dropping white Phosphorous on women and children etc etc --so carrying out a little corruption is not much of a leap.
