The reality on the ground indicates Israel may be preparing for the possibility of a much bigger war against Hezbollah in Lebanon. If so, the fight could get bloody.

Since Israel launched its ground invasion of Lebanon, Israeli forces and Hezbollah militants have clashed along the border while the Lebanese army has largely stood on the sidelines.

Hezbollah critics and supporters alike are voicing frustration over what many view as the group's miscalculations.

Israeli airstrikes have hit the headquarters of the U.N. peacekeeping force and other positions in south Lebanon in recent days, drawing widespread condemnation from around the world.
