President Trump approved an offensive cyber-strike that disabled Iranian computer systems used to control rocket and missile launches, even as he backed away from a conventional military attack in response to its shoot-down Thursday of an unmanned U.S. surveillance drone, according to people familiar with the matter.
The cyber-strikes, launched Thursday night by personnel with U.S. Cyber Command, were in the works for weeks if not months, according to two of these people, who said the Pentagon proposed launching them after Iran’s alleged attacks on two oil tankers in the Gulf of Oman earlier this month.
The strike against the Islamic Revolutionary Guard Corps was coordinated with U.S. Central Command, the military organization with purview of activity throughout the Middle East, these people said. They spoke on the condition of anonymity because the operation remains extremely sensitive.
Though crippling to Iran’s military command and control systems, the operation did not involve a loss of life or civilian casualties — a contrast to conventional strikes, which the president said he called back Thursday because they would not be “proportionate.”
The administration on Saturday warned industry officials to be alert for cyberattacks originating from Iran.

An this is what you call a proportionate response! Well done to US Cyber Command!
You do realize that China has not even closed the gap with the US economy in the last 5+ years?
