As military strategists in the West war-game a possible nuclear escalation by Russian President Vladimir Putin, they’re also pondering the role disobedience could play.

What if Putin gives the order to nuke, but others in the chain of command refuse to execute? Should the U.S. and its allies try to sway those individuals now?

Scenarios in which insubordination — from conscientious objection to outright mutiny — come into play aren’t far-fetched. If Putin were to escalate, he’d do it with so-called tactical warheads. These are currently in storage and would first have to be transported to launch bases and mounted on missiles. Dozens of officers would have to sign off and relay the order, knowing that Western spy agencies would be watching them at every step.
