Drones are not weapons of the powerful
Drones are cheap. They are just big radio controlled planes. They cost nothing compared to a jet fighter, and the technology is not hard. Islamic Jihad claims they might have one (who knows). Hezbollah is sophisticated, they built their own telecom network, for example, and tapped into Israeli soldiers cell-phones in the last war. They won the e-lint battle in that war.
Drones will spread, they are a poor man’s air force. They suck compared to jets, don’t let anyone tell you otherwise, but they are cheap, easy to make and easy to operate. This is only the beginning.
