There are still many, many uncertainties, challenges and difficulties in Afghanistan. But we have to enable the Afghans to manage those challenges themselves. We cannot solve all the problems for the Afghans.

As long as NATO changes when the world is changing, we will be very important for the security of all our allies, including the United States.

We are living in a world in which developments are harder to predict and one that has become more uncertain. In such a world, you must be prepared for the unpredictable. Nobody predicted the fall of the Berlin Wall or the Arab Spring.

Turkey has, of course, the right to protect itself against terrorism, against attacks, but I expect it to be done in a way which is in accordance with the rule of law, democratic values. And that is something I have expressed several times in meetings with the Turkish leaders.

When autumn darkness falls, what we will remember are the small acts of kindness: a cake, a hug, an invitation to talk, and every single rose. These are all expressions of a nation coming together and caring about its people.

Turkey's a valued ally, important ally for NATO, not the least because of its strategic geographic location, bordering Syria and Iraq and close to Russia and the Black Sea.

We are seeking to avoid a new Cold War, avoid a new arms race, and, therefore, we continue to work for a more constructive relationship with Russia, including political dialogue with Russia.

In the end, democratic societies are stronger and more resilient than any autocracy. And more adaptable too.

NATO is based on shared values. Democracy, individual civil liberties and the rule of law. In public and also in meetings with the allies, I have repeatedly pointed out how crucial these common values are. They are the basis for our unity, and unity is the most important basis for our strength.

But we have achieved at least two important things. Afghanistan is no longer a safe haven for international terrorists. We have a strong Afghan army, which is fighting the terrorists and Taliban. And the second thing is that they are able to do that without us being there to conduct the combat operations.

We see a more assertive Russia, which has implemented a very significant military buildup over several years, and a Russia which has used military force against neighbors, especially Ukraine.

Evil can kill a person but never conquer a people.

The answer to violence is even more democracy, even more humanity...
