Thus, on this World Refugee Day, let us take time to recognize and draw inspiration from these ordinary people who have shown such extraordinary courage - the world's millions of refugees and displaced.

...in the midst of migrants in search of a better life there are people in need of protection: refugees and asylum-seekers, women and children victims of trafficking...Many move simply to avoid dying of hunger. When leaving is not an option but a necessity, this is more than poverty.

What I think it's important to recognize in today's world is that all of our societies are multiethnic, multi-religious and multicultural. And that is a positive thing. That's a richness, and also strength. But we also have to recognize that, for those societies to be harmonious, there is a lot of the investment that needs to be made in social cohesion and inclusivity. But the important thing to recognize, and particularly Europe, most of the terrorist attacks are not done by people that came from the outside. They are homegrown.

While every refugee's story is different and their anguish personal, they all share a common thread of uncommon courage - the courage not only to survive, but to persevere and rebuild their shattered lives.

Syria has become the great tragedy of this century - a disgraceful humanitarian calamity with suffering and displacement unparalleled in recent history.

We need to be able to demonstrate that what we do in today's world, in humanitarian aid, the enormous effort to minimize the tragic situations that we see all over the world, I think, without the U.N., people would suffer much more, and the situation would be much more terrible.

It is, for me, clear that the world needs a United States that is engaged in security issues, in development issues, in human rights issues. The contribution of the United States for global affairs is absolutely crucial. And the cooperation with the U.N. is very important from our perspective.
