The Cold War isn't thawing; it is burning with a deadly heat. Communism isn't sleeping; it is, as always, plotting, scheming, working, fighting.
Those who remember Washington's cold war culture in the 1980s will recall the shocked reactions to Reagan's intervention. People interested in foreign policy were astonished when in 1985 he met alone at Geneva - alone, not a single strategic thinker at his elbow! - with the Soviet Communist master Gorbachev.
Since the end of the Cold War, Soviet aggression had been replaced by a number of particularly venomous threats, from Timothy McVeigh to Osama bin Laden.
I grew up during the Cold War, when everything seemed very tenuous. For many years, right up until the fall of the Berlin Wall, I had vivid nightmares of nuclear apocalypse.
There isn't a more important issue in the world than global warming. Even the Cold War and the Bay of Pigs crisis were a notional threat.
The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.
The Cold War is over. The kind of authority that the presidents asserted during the Cold War has now been diminished.
I give my grandfather, Dr Harold Young, a forestry Professor at the University of Maine, full credit for my career path. He pioneered the use of aerial photography in forestry in the 1950s, and we think he worked as a spy for the CIA during the Cold War, mapping Russian installations.
To declare the Cold War over, and declare democracy has won out over totalitarianism, is a measure of arrogance and wrong-headedness.
The '60s are my favorite decade - with the Cold War, the women's movement. And then there's the music, the fashion, the clothes, the hair.
