The IDF had plans developed over years that would have ended Hezbollah's existence in about a week. They called for extremely strong strikes against all Hezzie targets in Beirut at the onset of the war, in an attempt to kill Nasrallah and the rest of the leadership, or at least to prevent their easy escape. Simultaneously, Israel would land or airdrop troops far to the north of the border, and these forces would have worked their way south while the armored forces would have gone north. The Hezzies would have been surrounded on Day 1, and would have been leaderless and cut off from resupply from Syria & Iran.
Instead, (Fo)Olmert and his entourage eliminated the immediate air/sea landings, didn't allow ground forces in immediately and cut back on the Day 1 airstrikes - thus allowing Nasrallah to escape, most of Hezzie terrorists to escape, Syria/Iran to resupply those left, and causing over 100 dead, thousands wounded and a month of 1/5 of the economy being shut down. Not exactly what I'd call smart or decisive leadership - Olmert is Israel's Jimmy Carter and should be tossed from office as soon as hostilities are over.
There is no dismantling hezbollah, we know for a fact that hezbollah is a front for Iran, and Iran will continue to provide them with arms and personnel.
My prediction, and I might be wrong is that Isreal will lose this, and NATO will come in to "secure" the area.
I hope I am wrong.
I also hope I am wrong about the possibility that Olmert KNOWS they will lose and is sending these IDF troops into slaughter.
I must be wrong, I am sure I am.
