A much shared image on Facebook claims to show a comparison between the revitalization of Hiroshima after the atomic bombing of 1945, and the decline of Detroit since 1945.
However, it's not at all hard to find recent photos of Detroit that very closely resemble the "Hiroshima" photo, for example. http://www.aerialpics.com/E/nightskyline.html
Of course this does not mean that Detroit does not have significant problems with urban blight, nor does it say the Democratic administration is blameless in regard to this. However it does mean that the photo comparison is very misleading.
But what are the photos actually showing? For a start, the 2010 "Hiroshima" photo is actually Yokohama, near Tokyo. It's 400 miles from Hiroshima.
The Detroit 1945 photo is of Navin Field (later known as Tiger Stadium) in 1935, not 1945.
Tiger stadium was actually demolished in 2009, so we can't do a direct comparison, the area now looks like this:
But a much better comparison would be the actual Detroit baseball stadium, Comerica Park, which seems to be doing just as well as in the 1935 image:
The 2010 photo of Detroit is actually 2013, and it shows the Packard Automotive Plant, on the East Side of Detroit:

That site is currently being cleaned up for redevelopment, part of a gradual revitalization of the Detroit area:
Coincidentally, in the upper right of the actual Hiroshima 1945 photo:
There is now a demolished baseball stadium, the Hiroshima Municipal Stadium, which was demolished in 2012, almost exactly the same as Detroit.
If we are to take the same approach as the misleading meme, the area in Hiroshima now looks like this:
