The fall of communism around the world, as exemplified by the fall of the Berlin Wall and the unification of Germany would certainly strike me as an important world event. As did a previous responder, I also grew up in the time of bomb shelters, "duck and cover" drills, fear of when (not if) a nuclear war would break out. All of this, of course, was punctuated by the Cuban Missile Crisis. We truly lived in a bi-polar world at that time, and no solution short of war was on the horizon. The fact that these trying times ended, in T.S. Eliot's words, "not with a bang, but a whimper," is truly significant.
