First of all, I would say that this would be a total disaster for NATO. This would be a failure for NATO.
In our report, we described a few scenarios that could happen. There could be a civil war, or the country could be occupied by Pakistan, on one side, and by the Northern Alliance, on the other, which would result in a partition of the country. There are a number of possibilities.
In my opinion, the consequences of a quick withdrawal from Afghanistan would be very difficult. That is why I said it was not an option. We need a different strategy to get out of the country, not a quick, full withdrawal.
