The Confederacy has a long memory, and some of their numbers have also made a trek from west to east (specifically some Pacific North-Western tribes have joined the Confederacy) so even if Cockburne's army tried to make amends, they'd find themselves quite rapidly facing the wrong end of Confederacy miniguns. Definitely some common history there though.

Fair enough, they'd probably just restrict contact to having nightkin kidnap people every so often then, as the migratory tribes in particularly would probably have a bad member of the supermutants (hell some of them could have been refugees from Cockburne's onslaught in the first place).
