CALIXTINE

Okay, if we change the X to B we get INCITABLE, like a near-riot

or change the X to M and get MILITANCE, which is North Korea's posture at the moment

but those are both on the forced side. I like better changing X to S, which lets us be
INELASTIC

(extra credit: X -> C is for Leibowitz, almost, if you drop the second I)
