I don't know much about it, but doesn't the MOAB have a signficantly greater ability to bomb deeply-dug in troops? I'm all for routing the Islamofascists from off the face of the earth, but shouldn't every effort to reduce the loss of troops be utilized before sending them in.
To me, not doing this is on a par with all this UN nonsense about cease-fires, peaceful solutions, etc. It's taking the kinder, gentler road, when what is necessary to minimize the loss of life is to demonstrate to the enemy a clear, decisive willingness to rain more death on them than they could ever imagine (or be willing to endure).
Admitting that I don't know a lot about MOAB myself, I think that it's really caught on in pop culture but I don't know the practical utility of it. If I recall correctly, it has to be dumped out the back of a C-130, and is unguided. My gut feeling is, as soon as the politicos get out of the way, the IDF will do what it does.
And the IDF is very, very good at what it does.

MOAB - Massive Ordnance Air Blast Bomb
http://www.globalsecurity.org/military/systems/munitions/moab.htm
...The 21,600-pound MOAB is an improved replacement for the unguided 15,000-pound BLU-82 Daisy Cutter. It is 30 feet long with a diameter of 40.5 inches. The warhead is a blast-type warhead. It was developed in only nine weeks to be available for the Iraq campaign, but it was not used in combat.
...Contrary to some reports, it is not capable of deep ground penetration.
...Unlike the Daisy Cutter, the MOAB falls to the ground without the use of a retarding parachute. As a result, the aircraft releasing the bomb can fly at higher altitudes, thus making it safer for US pilots.
...The MOAB weapon kills by way of blast or fragmentation. Blast and fragmentation are historic and common anti-personnel effects in lawful military weapons. There are no components that would cause unnecessary suffering. The explosive ingredient H6 is a widely-used explosive that is typical for weapons of this type. The components RDX and TNT do have some potential toxic effects from long-term exposure, but these are limited and within US government tolerance levels. The potential psychological effect of the weapon does not constitute suffering. The intent is to demoralize or frighten the enemy by impressing them with the large footprint, resulting cloud, and tremendous noise of the explosion.
