Refugees have been displaced by war or natural disaster or political catastrophes, and they are much more threatening because they are reminders to people that all the comforts that we take for granted can be taken away in just a moment.

Refugees are threatening, not just to Americans, but also in many countries the world over. And it's partially because, unlike immigrants, refugees do not choose where they're going to go or why they're fleeing, and they are unwanted populations. They bring with them the stigma of disaster.

40, 50 years ago, Americans - the majority of Americans did not want to accept these Vietnamese refugees who they saw as completely foreign. Now there are new foreigners - Syrians and other people from the Middle East, people of Muslim backgrounds. And the sense among many Americans is, well, these people are completely different from us, and they're not like the Vietnamese who are much more assimilable. And I think that's very, very doubtful. I think that the majority of these new foreigners, if given the opportunity, will be able to assimilate and deal with American culture.

I've never stopped being a refugee.

Immigrants who come to a country are going to lose something, for sure, but they hope to gain a great deal by making this journey, whereas refugees by definition have lost a tremendous amount - not just country and society, but also more personal things like careers, prestige, status, relatives, identities. This inevitably makes the longing to remember the past even more powerful among refugees, to the point of often debilitating them.

In the United States, the immigrant experience occupies a very central place in American mythology. And sometimes, that place wavers between acceptance and rejection.

No one wants for their child to become a refugee. It's an awful experience.
