Alexander the Great conquered the world. Rome imposed pax Romana. Russia cut the window on Europe. British empire spawned continents. Napoleon liberated Europe. Europeans pioneered America. Jews restored their ancient state.

Israel’s only chance of entering the history is becoming the Great Israel. Regardless of her enemies’ lives.
