Ten years ago, scholar John Arquilla coined the phrase "net warfare" to describe an unconventional way of fighting. He says the wars in Iraq and Afghanistan, as well as the current conflict between Israel and Hezbollah, show how independent units of fighters can use networks to take on larger, better-equipped armies.
In the Middle East, Iraq and Afghanistan, fierce resistance from militants has given military experts a lot to analyze.
And in southern Lebanon, Hezbollah militants are firing as many rockets today as they were when the conflict began three weeks ago -- despite taking a constant pounding from the well-armed, well-trained Israeli Army.
Michele Norris talks with Arquilla, who is a professor of defense analysis at the Naval Postgraduate School.
