Hezbollah and the IDF

HEZBOLLAH AND THE IDF….OK, genuine question here. Hawkish commentators have been filling the airwaves and printwaves with declarations that the war in Lebanon can’t end until Israel destroys Hezbollah once and for all. But putting aside for now the question of whether that’s good policy ? a world without Hezbollah sure seems like a good idea ? what makes anyone think Israel can accomplish this? The IDF spent nearly two decades in Lebanon until Ehud Barak withdrew in 2000, and presumably was doing its very best during that time to destroy Hezbollah. But they weren’t able to do it. So what’s changed since then to make us think that the IDF can do it now?
