We work at two levels in Afghanistan.
First, we train Afghan forces so that they will be able to ensure their own security. At the other level, we try to promote more generally the country's development. NATO's strategy is to ensure—
focus on training the Afghan forces over the next two and half years, so that by the end of 2014 they can look after their own security. Assuming a fair measure of success, at that point there is a question: are they capable of handling their own security? How much continued military support is going to be required beyond 2014? It's a big question mark, and I don't think any NATO country has officially declared that it is willing even to think about that issue just yet.
On the other hand, a NATO strategy was approved at the Lisbon summit, which will be revisited at the Chicago summit next weekend, about continued support for Afghanistan over the long term in finance, economics, social development, education, and so on. There, there seems to be a good deal more willingness to stay involved in Afghanistan, but the question will be how much can people afford, and how much do they want to do in Afghanistan, given their own economic weaknesses?
