Wall-less Europe

When the wall came down 20 years ago it was the end of a regime whose cruelty was vividly represented by images of the lengths to which it went to keep its citizens within its borders. Who can forget the images of cars being searched as they exited Checkpoint Charlie; border guards doing their utmost to find even the most ingeniously hidden escapee. How can we not remember the dark inventiveness with which a regime seemed to turn every technological advance against its own citizens? How happy one could feel to be a citizen of the free world: free to travel across our own borders with governments who respected our personal liberty not only in this context.
