" When the term “cyber war” is used in this book, it refers to actions by a nation-state to penetrate another nation’s computers or networks for the purposes of causing damage or disruption. When the Israelis attacked Syria, they used light and electric pulses, not to cut like a laser or stun like a taser, but to transmit 1’s and 0’s to control what the Syrian air defense radars saw. "
