Sarkozy was the one who appointed him in the first place.
In order to get him, a bitter political rival, out of the country. That M. Strauss-Kahn has since not just apparently stepped on, but apparently ran in place on his 'homme-hood' makes M. Sarkozy's decision to be wise, indeed...

Sarko appointed DSK to the IMF to get his most powerful potential political challenger out of France.
