Looks might ugly. And getting uglier. As crappy as that peace accord was, it was .... peace. If all bets are off, does Israel get her land back?
If protesters intend to attack Israel, how will they replace the Aswan dam? Can Egyptians survive for 938 years in a radioactive slag heap?
Over one half of Egyptians suffer from birth defects including mental illness and retardation.
