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.

The international community has to overcome its differences and find solutions to the conflicts of today in South Sudan, Syria, Central African Republic and elsewhere. Non-traditional donors need to step up alongside traditional donors. As many people are forcibly displaced today as the entire populations of medium-to-large countries such as Colombia or Spain, South Africa or South Korea.

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.

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.
