The CW has proven that the chain of command in all participating countries with nuclear weapons is quite effective at filtering out the suicidal schizos or troons that just want to see the world burn. And even if this particular breed of lowlives worms its way into the driver's seat of a nuclear armed nation, you can bet the people right below them would frag them if the order of a nonsensical suicide attack was given. I'd be more worried about accidents like diversity hires fucking up the maintenance of a nuclear missile.
