I've just realized I don't understand what this phrase means. What does "Gaddafi is on the wrong side of history" mean?
Does it mean he's about to die, or something else? Here's the relevant quotation:
The Libyan leader, Muammar Gaddafi, is "on the wrong side of history," said U.S. president today. In a joint press conference with President of Mexico, Felipe Calderón, Obama said his country is studying "a whole range of options" to apply in Libya, but downplayed the possibility of military intervention, saying that "what want is to have potentially the capacity to intervene quickly if the situation deteriorates".
