Terran won't attack the Zuma. For all their bluff and bluster about being the military power of the 'Moot they are relatively weak. Kabrinskia has almost as much CS as they do and we are second on Dwilight for CS per noble. Terran has 100% more wealth than Kabrinskia yet only 10% more military.
That just adds to my suspicion that Terran is working with the Zuma. 
D'Hara has about the same total CS as Kabrinskia, and we aren't even trying to field an army. Terran doesn't have much reason to either.
