Wasn’t Detroit once a city?
From Wikipedia:
Between 2000 and 2010 the city's population fell by 25 percent, changing its ranking from the nation's 10th largest city to 18th. In 2010, the city had a population of 713,777, more than a 60 percent drop down from a peak population of over 1.8 million at the 1950 census, indicating a serious and long-running decline of Detroit's economic strength
The conclusion is inescapable. We have to nuke Detroit.
