Ideally you don't want to be in a situation where a strike against you is the obvious choice, AI or not.
There's always been sabre rattling throughout history. I'm not sure "AI says so" is much better than "the numbers guys say so" or "the chicken bones say so."
What you describe is different from sabre rattling. It's the contrapositive. Sabre rattling is just emphasizing you have the capability and willingness to use violence.
Claiming "the AI says so" or delegating to some other fail-deadly or dead hand device is rational irrationality. It's telling your opponent that you lack the capability to not use violence. By forcing your own hand, it forces their hand.
