Many commentators thought that the recently voted ceasefire to the fighting is Lebanon would fail, but for perhaps different reasons than it is looking right now to actually be happening.  Pundits far and wide assumed that the Lebanese government would at least go along with the perception of deploying troops according to the agreement to occupy the territory currently under Israeli control.  But Hizbollah won't let them get even that far:

Lebanon's cabinet indefinitely postponed its meeting.

After five hours of discussions on Saturday, it had agreed to accept a UN Security Council ceasefire resolution with reservations.

The second gathering was meant to consider the details of implementation.

However, the issue of Hezbollah's disarmament and its military presence in southern Lebanon continues to cause major tensions within the fragile government, our correspondent reports.

He says that without a meeting and an agreed plan, it seems that the deployment of 15,000 Lebanese army troops to the south is unlikely to go ahead.

Even if the planned ceasefire happens, the prospects of continuing skirmishes on the ground will remain high, he adds.

Hezbollah, a member of the government, says it will abide by the resolution but retains the right to continue attacks until the last Israeli soldier has left Lebanese soil.

A cease fire isn't a cease fire if one party to the fighting just keeps firing.  That's an oxymoron isn't it, the total opposite of the stated goal?  And a contract is no longer binding if one party refuses to comply with specified portions of the contract… such as moving troops into the area of fighting to enforce the peace and disarm Hizbollah.  Lebanese refusal to even pretend to comply with such major elements of the agreement end the paper agreement before it has really even begun.  Which means the whole "cease fire deal" is dead.  Or it should be.  Captain Ed at Captain's Quarters thinks so:

As expected, Nasrallah and Siniora have let Israel off the hook — and provided the political cover for further military action against both. If Lebanon refuses to abide by the terms of the cease-fire, expect the UN Security Council to wash its hands of the issue.

I suspect he is right about the first part but I'm quite skeptical of the second.  Will the U.N. Security Council, for perhaps the first time in its existence, act rationally and reasonably in recognizing the plain fact of the failure of this effort?

I don't see why.  Why would they start now?  Blatant failure and results exactly the opposite of those supposedly desired are common with the U.N. but its never really phased them before.  Somalia, Rawanda, or Sudan come to anyone's minds?

The U.N. is most feckless when it comes to dealing with the Middle East and Israel.  Do you think the member nations of the U.N. Security Council are really interested in giving Israel fair treatment?  Decades of one sided "resolutions" that scold Israel and make every attempt to protect and assist its enemies make plain the international prejudice against Israel.

If the Lebanse utterly fail to even attempt to keep up their side of the bargain I would expect the U.N. to do exactly what it has always done to Israel:  hold it to a unique double standard and demand that Israel comply to the letter with the agreement even though other parties are not even making a pretense about complying with their portion of the deal.  Just like the Oslo "Peace Accords", which were a sick joke since the exact opposite happened in an ongoing way with higher death totals than ever before from terrorist attacks on Israeli civilians.  Israel was expected to keep complying with every element of its part of the various negotiated bargains while the Palestinians were expected to violate every agreement and keep killing Israelis.

The current global reaction in placing blame on Israel for the current conflict only reinforces the same prejudices.  I find it hard to see how Israel gets better treatment now from the "International Community" than it was when it wasn't invading a neighbor to world condemnation.

I'll make my own prediction.  I predict the U.N. will ignore the "delays" in compliance of the Lebanese, Hizbollah, and U.N. forces while demanding immediate and full compliance from Israel regardless.  The question to me is, what will Israel do about it?
