Catch-22

Have you ever seen a circle? How about this one:

Lebanon will not put its troops into South Lebanon until Hezbollah is disarmed.

Hezbollah will not stop fighting until Israel leaves South Lebanon.

Israel will not leave South Lebanon completely until there is some sort of Lebanese force in place to subdue Hezbollah.
