I think any reasonable Councilman would go "We enjoyed the stability and safety of Baffin, it's kept us safe too. No reason to jeopardize that just to prove a point, it's a futile effort. Just set bases to engage GRN if they should happen to venture this far and find Baffin; but don't provoke unnecessary hostilities with the Outcasts".
I think a Colonial would go "Burn them, set bases to kill all the Outcasts, we'll support you to the best of our ability; but the bulk of our resources are aimed at building our new home".
And I think GRN would take a break from spanking Outcasts if they found out they're making a move on ze arch-nemeses, namely Council and CR and to a smaller extent TAZ.
