The stand of the "realist" school, and its objections to further or faster involvement in the Libya crisis, can be fairly summarized...The actual evidence, however, is that Qaddafi senior has reached his Ceausescu moment: a full-dress (in the literal sense) meltdown into paranoia, megalomania, and delusion. His recent speeches and appearances have shown him stinking with madness and hysteria. His age and condition, at any rate, set a very sharp limit to the duration of his regime. If that regime implodes while he is still "in place," then all the grim consequences foreseen by the realists will be incurred in any case. Weapons will get into the wrong hands; divide-and-rule tactics (already a stock in trade) will intensify; religious and tribal passions will be deliberately inflamed. The main difference will be that we merely watched this happen.
