Well, let's see... First, I think it would be good if we could get a list of Zeon's assets from Apologized. Once we know what we have t work with, then we can better decide what to do next. Whether to go for Jaburo and Luna 2, one or the other, or neither. Granted, it is slightly meta since David probably doesn't know the exact disposition of all Zeon's forces, but he might ask Garma IC as the justification for that.
Also, I think now that it's pretty apparent that the war is coming to a close, it would be best to slow down development of new Mobile Suits and instead work on producing as many of the high-end suits as we can. If we can make it so that no frontline pilot is using anything less than a Dom or a Gouf, that should help our forces. Quite possibly more than sticking with Zakus for most with only a handful of Gelgoogs and Gyans, etc, for the elites.
