Reconquer the streets, the markets - the public spaces, with the same message of opposition: We are devastated, but we will not give up. With torches and roses, we deliver this message to the world: We do not let fear break us. And we do not let the fear of fear silence us.

We are deploying battle groups, battalions, which we consider necessary to convey a message of deterrence, credible deterrence, that if one NATO ally is attacked, it will trigger a whole response from the whole alliance.

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.

We had very good discussions on current security challenges and NATO's continued adaptation to meet them. Canada is a committed ally and a capable contributor to international security. We appreciate your quick decision to deploy forces, planes and ships to strengthen our collective defence in view of Russia's aggressive actions in Ukraine, as well as your contribution to the international anti-ISIL coalition. Canada plays a major part in our decision-making and helps keep the vital bond between Europe and North America strong.

What NATO troops are doing in Afghanistan is to train, assist and advise Afghans, but they are actually doing the fighting. They are actually taking the responsibility for the security in their own country. And that is a great achievement, compared to what we saw just a few years ago, when NATO troops had to conduct the combat operations fighting the Taliban.

Evil can kill a person but never conquer a people.

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.
