Don't you think having your ZOI go into Kusari and the very areas you are 'cut off' from is a bit much?
The whole point the Kusari Exiles were created was due to the Taus being impenetrable and they couldn't return to Kusari. With this ZOI you're also butting heads with the current Kusari forces, which could not sit will with your forces.
EDIT:
Wait Wait Wait. The -POLICE- go to the Exiles? Not only does that make almost zero sense, you're flooding a bunch of bushido warriors with civilians. There is no reason for this to occur, nor is it explained.
