It's the ninth day of heavy fighting in Southern Lebanon. Israeli jets bombard the region, while special forces battle with Hezbollah troops on the ground. What is Israel's military strategy?

Israel faces a quandary in its conflict with Hezbollah: There can be no end to the conflict in Lebanon without ground forces securing the border, but no government in Israel will want to leave Israeli troops in Lebanon for long.
