The answer to yesterday's question is: true. Americans used the air base at Keflavik throughout the Cold War.
Personal side note about Keflavik: I got out of the army in September 1990 and didn't find a job until March 1991. You might imagine that was a difficult time for me, and you'd imagine correctly. Anyway, not more than a couple of weeks after finally getting a job, I got a call from the army's personnel center in St. Louis. They told me they needed an officer to go to Iceland for 6 months, and (for some reason I cannot fathom) my name was at the top of the list.
Had I not just landed a job I'd have been on the next available flight, but I couldn't accept a job and then turn around and leave because I just received (what I would consider to be) the offer of a lifetime. My integrity is worth more than that, so I've waited an additional 24 years to go to a land I've wanted to visit since I was 9 years old, when I saw it from the window of an airplane from 39,000 feet.
Today's question is: in what year was the (failed) Reykjavik Summit between President Reagan and Mikhael Gorbachev?
