I forget the details but I think there is some rule about temporarily gifting cities and units for upgrades.
I think part of why they don't attack, is they don't want to have to damage their economy even more. Even if they gained cities it would streach their borders alot along with requiring a lot of worker infrastructure to get everything going again.
The thing I haven't seen Speaker or Sulla mention is that their new city Kassite has buddhism in it. Doesn't that give Kathlete vision on the city? That might prove interesting in the future.
