I would say that the $27 billion figure I mentioned did not adequately consider the cost of security, and I agree with you there. That's why, for example, the recent U.S. contribution of $8.6 billion, just in the next couple of years, to rebuild and to sort of jump start the training of the Afghan security forces shows that the original figure was not adequate.
So I imagine that significantly more resources than that will have to be dedicated to the Afghan security sector alone. I feel reluctant to give an overall figure that we'll see. But it will certainly exceed that $27 billion significantly when you take into consideration security sector reform. When you consider the international troop deployments, we're talking about a significantly larger number.
