Is Israel Deliberately Violating the Ceasefire in Lebanon?

From Juan Cole's Informed Comment:

Lebanon says that the Israelis made a commando raid into the Biqa' valley, attacking a village near Baalbak. The Lebanese maintain that they foiled the raid.

MSNBC was discussing this today as well.

Unfortunately, one of the chief reasons Israel becomes such a target for attacks is that they - again and again - treat all neighboring countries like they own them so they move in to do whatever they want, assured that the U.S. will always prevent the U.N. from taking action against them.
