If the countermeasure is to jam the nuke's communications, then the obvious response is to rig the bomb to detonate automatically if it loses contact
Not even the craziest nuclear states have implemented a nuclear device that fails unsafe. In all cases, a chain of all-in-agreement affirmative steps must be taken to arm, target and detonate a nuclear device. If someone implemented the scenario you describe, they have just handed a free nuclear weapon to anyone who can cause a comms jam. $BADACTOR can hold everyone to ransom by holding the comms offline and demanding a payout (or a release of prisoners, or whatever they want).
