President Obama has said that our aspirations should be realistic. We are not going to turn one of the poorest countries in the world, that was plunged into 30 years of war, into an advanced, industrialized, Western-style democracy. What we want to achieve is Afghanistan's capacity to secure and govern itself.

I think Putin wants to recreate as much of the Soviet Union as he can through a variety of different means. He's invaded parts of Georgia, took Crimea, southeastern Ukraine, bases in other countries.

Iran, as we have already discussed, has carried out very, very harmful activities inside Iraq. Funding, trainings, arming and, in some cases, even directing the activities of the special groups associated with the Jaish al-Mahdi and the Sadr Militia.

We cleared many of their towns and cities and rural areas of al-Qaida Iraq and other insurgents.

Over the last few years they have done a superb job in their fight against al-Qaida. As you may recall, our embassy in Jedda (in Saudi Arabia) was overrun some four years ago and a number of foreign workers went home because of violence against them.

Every civilian's death diminishes us, collectively.

The art of coalition command - whether it is here in Afghanistan, whether it was in Iraq or in Bosnia or in Haiti - is to take the resources you are provided with, understand what the strengths and weaknesses are and to employ them to the best overall effect.
