David Warren drips with sarcasm but nonetheless states his case, doesn't he?

Should the Americans withdraw from Detroit?

While they have been able to hold Detroit since General Harrison recaptured it after the Battle of Lake Erie (in 1813), hardly a day now goes by in which there is not an ambush or a killing. The rate has been rising through Detroit's notoriously long hot summer.

If the standard is one killing per day -- the current average in Iraq is a little less than that -- then the U.S. should also withdraw from Chicago, New York, and Los Angeles. An analysis of the statistics, in proportional terms, suggests further quick withdrawals from Memphis, Dallas, Baltimore, Philadelphia, and of course, Washington, DC.
