You're statement "Reagan accomplished the peaceful dissolution of the Soviet Union using trustworthy statesmanship and diplomacy, without firing a shot" is only true in the sense that Regan himself never fired a shot. Otherwise its nonsense.
Untrue disingenuous weasel words.
Reagan never ordered nor knowingly allowed ANY military engagement connected to his negotiations on the dissolution of the Soviet Union.
Reagan only promised to build (and share) an ICBM anti missile defense system.
