Is it possible that an incident involving soldiers, tanks or any other troops or troop parts, with at least one fatality on both blocks' sides, at the Fulda Gap in the time from August 13, 1961 to November 9, 1989, does not lead to global thermonuclear war?
If this is possible, how? What would such an incident look like? and what would the effects on Europe (territorial changes, regime changes,...) and the world be?
