I have one more very brief question. I'm going over old territory covered by my colleague.
You have seen the piece by one of your colleagues, General Manson, “A Rational Exit Strategy for Afghanistan”. He lists a certain number of indicators that he believes ought to crystallize before a rational exit can take place, and he says that in fact he can't tell how long it would take.
When I read these indicators, which indicate the Taliban decline, security being restored, the Afghan army and police becoming effective, market economies locally beginning to flourish, human rights increasing dramatically, central government control spreading, the development of infrastructure, democratization—all of these things that we know in the west to be important preconditions for a stable society—I'm not asking you to look at your crystal ball, but would it be fair to say this could take 20 to 30 years in Afghanistan?
