There are certain Rules of War regarding the use of nukes. If Side A uses one, then Side B may use a bigger one, and then it escalates. In addition, nukes tend to generate nuclear fallout, whereas a MOAB doesn’t. So, you could use a MOAB to clear an area of hostile troops and then move your own troops safely into the area, without worrying about radiation poisoning.
