Expect Hamas to usher civilian shields into these tunnels (or "air-raid shelters" if you prefer), where the terrorists will hunker down as well.

Problem for Israel: get the bad guys and their weapons out, while trying to recognize and spare the unarmed citizens.

On Iwo Jima, it took U.S. Marines more than a month to pry the Japanese out of eleven miles of such tunnels. Hamas allegedly has 300 miles. And the Japanese didn't use human shields to generate world outrage.
