What were the new technologies of the cold war?

The cold war was a "military stand-off", NOT a shooting war. It was equivalent to two frontier gunfighters facing each other in the street...but neither one reaching for his gun...just staring at each other, waiting for the next move. In 1990 (actually in 1989 when the Berlin Wall came down) one of the gunfighters turned his back to his opponent, and walked away...ending the stand-off (the Soviet Union collapsed). The technology used during the cold war; was part of an ARMS RACE. The only time those new "Arms Race" weapons were used in combat was during the Korean and Vietnam Wars (Example: F-86 Sabre Jets in Korea & F-100 Supersabres in Vietnam).
