The chaos gods in no way keep long alliances but primarchs still keep alliances.I could be wrong but I dont know of once instance in 40k where a Chaos legion held a long war against another chaos legion.But one thing is for certain,if the loyalist primarchs came back into action,the traitor primarchs would defenantly form a strong alliance to crush them.
