Zoologists get pretty excited when they discover an unusual animal. They happily devote many hours to the task of classifying the beast and, if it qualifies as a new species, giving it a name. A great deal of money and prestige rides on these scientific endeavors. The same applies to the political sphere, where new and unusual creatures frequently turn up. When it comes to Barack Obama, however, political zoologists remain undecided whether he is a new kind of political animal and if his foreign policy represents a unique departure from the same old, same old.
