Today is the twenty-fifth anniversary of die Wende - the fall of the Berlin Wall and the ending (until this year, maybe) of the Cold War between communist Russia and its satellites and the West. SED central committee spokesman Gunther Schabowski, announced changes that would allow GDR citizens to apply for visas to travel aboard, "immediate, without delay". The latter sentence was the key - there were no plans in place by the SED for immediate travel, but Berliners weren't worried and streamed across the border after demanding gates were opened
Europe has changed so much since then that it's easy to forget the continent was utterly divided by an barbed wire and concrete barrier, separating German from German.
It is the leitmotif running through much of the best Cold War fiction and continues to fascinate as history and fiction.
In Berlin Game, Len described it I thought very well:
"Spiked through both sectors, like a skewer through a shish kebab, ... the East-West Axis"
