Open questions:
What happens if the “Russian tactical nuclear device” is actually a clandestine/false-flag device detonated under NATO auspices?
What happens if the Russians actually believe in a barrage of “tactical” devices against NATO HQ and other rear positions instead of a single weapon demonstration under the so-called “escalate to de-escalate”* concept?
