I think there are a lot of things that are in play here (aside from the fact that the "resolution" had been delayed by Bolton for weeks and that it is pretty toothless anyway).
One is that this was all a preliminary, testing skirmish. Ohlmert revealed himself to be too weak and vacillating for us to support fully, because, quite frankly, I think he would have let us down and made us look a lot worse if we had overtly committed and then he wimped out. I would suspect that Bush is a little disappointed in Ohlmert's performance, after Israel had been given the time and strategic materials to carry it off more thoroughly than it has.
Secondly, I think Hezbollah proved to be a lot better armed and more widely dispersed than anybody expected initially. I am sure we were watching their means for receiving their resupply shipments, who was sending them, etc.
Third, I think it indicates that the nutcase in Iran isn't quite ready to go yet; while he blustered, he really didn't do anything overtly, but limited himself to covertly supplying advisers and materiel to the Hezzies. It also revealed that other countries which may hate us, such as Saudi Arabia and Egypt, are more afraid of Iran than they are of us, and are even willing to support us rather than be taken over by Iran.
There are a lot of things going on here, and this is probably just one of the opening skirmishes in a war that we have to win - so therefore, we have to conduct it correctly and knowledgeably from the start.
We more than likely have more in common than not, but I have an entirely different take on this. But perhaps I am, due to age and past experiences, a bit jaded.
I, personally don't give a hoot about how "we look" and deeply believe that "we" have been squandering in many ways the chance to take this conflict of civilizations directly to our enemies directly by following the Military ancient and in recent histories ignorance of the "principle of mass".
If you are at all interested in the "principle of mass" as taught at the Army War College for many decades now you may read about them at the following link.

As in a "war" I participated in 30 plus years ago, we seem to apply them for a while and then back down.
What a waste of time and resources putting off the inevitable is and always has been.
