I'm living the dream.

I just don't know whether it was all destroyed years ago - I mean, there's no question that there were chemical weapons years ago - whether they were destroyed right before the war, (or) whether they're still hidden.

The question is always how you get the number of troops needed. They do not have to be coalition forces. We also have to expand the training program for the Afghan National Army and the national police, in particular. and Defense Secretary Robert Gates has already announced support for a significant increase in the Afghan army.

In Afghanistan you are not rebuilding, you are building. There is very limited infrastructure and extreme terrain, with deserts in the south and mountains so high in some areas that helicopters don't even fly well at a certain altitude because the air becomes so thin. The country has a serious problem of illiteracy, especially after so many years of war and Taliban rule.

Even the Interior Ministry in Riyadh was hit. Since then, the Saudis have employed a very intelligent and comprehensive approach to counter al-Qaida, including precise operations based on good intelligence, changes in their corrections facilities, superb strategic communications programs and a host of other initiatives - all of which, together, have helped Saudi Arabia achieve impressive results in their fight against extremists.

If you look at casualties, you find countries that had much higher loss rates per capita than the US. Denmark comes to mind, the United Kingdom, they have suffered heavy losses at various points, the Germans as well.

The Islamic State fighters in Mosul are dead men walking and I think they increasingly know it.
