His son
Hannibal Gaddafi and daughter-in-law were arrested for allegedly beating their servants at a hotel, detained for two days and then released. He took it quite personally and this lead to a two-year-long diplomatic crisis between Switzerland and Libya, with Swiss assets in the country being shut down, flights canceled, billions of dollars withdrawn, two businessmen being arrested and held hostage, and Gaddafi himself being quite adamant that Switzerland was a land of infidels that needed to be destroyed.
Oh, and this proposal? It was made at the 35th G8 Summit. Publicly.
Basically, it was one huge tyrannical temper tantrum.
