I think that it's very important to have the United States' engagement in many situations we have around the world, be it in Syria, be it in the African context. The United States represents an important set of values, human rights, values related to freedom, to democracy. And so the foreign policy engagement of the United States is a very important guarantee that those values can be properly pursued.

Now, it's high time for all those that have an influence on the parties with the conflict to understand that it is in the interest of everybody to put an end to this conflict.

When food becomes scarce, refugees often turn to desperate measures to feed themselves and their families. We are particularly worried about the health of the refugee population, domestic violence and refugees resorting to illegal employment or even to prostitution, just to put enough food on the table.

We can't deter people fleeing for their lives. They will come. The choice we have is how well we manage their arrival, and how humanely.

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

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.
