I think this is a temporary situation because no sufficiently powerful entity has invested sufficiently much in AI-based defence. If this situation persists without any major shift in power for long enough, then it will be because the US and/or China have made an AI system to automatically suppress AI-powered gangs, and maybe also to automatically defend against AI-powered militaries. But the traditional alignment problem would to a great degree apply to such defensive systems.
