In recent times US grand strategy has been guided by a new kind of doctrine, named after not its author but its exemplar: the Costanza doctrine.Not much new beyond that, but worth a glance.
This doctrine, which had its heyday in 2002-2004 but remains influential, recalls the classic episode of the TV comedy Seinfeld, "The Opposite", in which George Costanza temporarily improves his fortunes by rejecting all the principles according to which he has lived his life and doing the opposite of what his training indicates he should do. As Jerry tells him: "If every instinct you have is wrong, then the opposite would have to be right."
The Iraq policy pursued by the Bush administration satisfies the Costanza criterion: it is the opposite of every foreign policy the world has ever met.
George? Are you master of your domain?
