ALONG THE ISRAEL-LEBANON BORDER - At a remote Israeli outpost along the northern border with Lebanon, every day is a potentially deadly game of cat and mouse, with the terror group Hezbollah only yards away, flying its flags. Israeli soldiers in high-tech observation stations monitor cameras and sensors around the clock. The situation became even more volatile, when in November and again on Monday, Hezbollah surprised the Israelis by launching unmanned aerial vehicles, or UAVs, that flew over Israeli towns and returned safely to Lebanon. The leader of Hezbollah bragged at a rally that the unmanned surveillance plane, called Mirsad 1, can be rigged with explosives and flown deep inside Israel.
