American People: As is often the case, the American people are way ahead of Congress on this issue. And not being sure, like a majority of Britons, I cannot conceive what victory might look like.
Length: Afghanistan is now the longest war in American history, passing the boondoggle in Vietnam. Nobody has managed to do anything there but die and now we have a corrupt government to support. The question now is who will be the last British soldier to die for politicians' blunders and vanity?
The third reason for us to maintain troop strength in Europe — and bases from which they can operate — is even stronger than it was at the end of World War II. And Afghanistan is in the midst of an internal struggle to weed out corruption and form a legitimate democracy.
Brown's definition of necessity, then, is an odd one.
