Need to capture Antietam to cut Spullla metal permenantly, or manage to pillage it and interdict the tile. That's not an easy thing to do. OTOH, Spullla are going to be massively hampered by unhappiness with all of the whipping that they'll be doing, with the associated loss of teching ability and growth.
I don't think Spullla will die, but I don't think they'll get a peace deal out of it, in which case they are going to have a very hampered growth period afterwards.
