This guy has been crazy all his life. His rigid sense of rightness, demonstrated in the video below, is scary. He can't tolerate different opinions and views. A classic case of an authoritarian personality.
I'm surprised that an intellectual nation like Israel elected this man who only uses emotion and throws logic aside. Then again, not really. Germany, the most intellectual nation in Europe, elected the demagogue Hitler. So any country, no matter how civilized, can slip up mentally and become a victim of emotion-based, fear-mongering rhetoric. America, Israel, England, Germany, Russia, Iran, France, the country doesn't matter. We're all humans - emotional creatures who can be easily manipulated, easily led to war, and easily hoodwinked by men in power.
