Nakasone Jokes

I heard Mort Sahl tell this story about Al Haig on the CBS
morning TV program on March 24, 1987; this version is
paraphrased from my notes.
When Prime Minister Nakasone visited President Reagan, he
asked for the auto import restrictions to be rescinded,
saying ''We've had a rougher time of it; consider
Hiroshima.''
The Gipper was nonplused. ''What has that got to do
with it?''
''Well, we've never destroyed one of your cities,''
replied Nakasone.
Quickly Haig cut in: ''What about Detroit?''
