I think that is a responsibility we all share as Americans. But as State Department employees, we have a special duty to guard ourselves and our sensitive information. Complying with department policies and being alert to potential threats will help protect all of us.

It does not matter what country we live in, who our leaders are, or even who we are. Because we are human, we therefore have rights. And because we have rights, governments are bound to protect them.

I think that, given the threat that ISIS poses to the region and beyond, as we have sadly seen in our own country, it is important to keep the Iraqi army on a path where they can actually take back territory, to work with the Sunni tribes in Anbar province and elsewhere so that their fighters can be also deployed, to work with the Kurds to provide them the support, but they're doing the fighting. We're doing the support and enabling.

We've got this arc of instability from North Africa to South Asia, and we have to pay close attention to it. And we have to build coalitions, something that I did to take on the Iranian nuclear program, and what I will do as president to make sure that we defeat these terrorist networks.

Sometimes, opening up your eyes and realising what you have - no matter how little you think - helps you find yourself.

There are things we can do [with violence], and we ought to do it in a bipartisan way.

The Russians need to understand. I think they've been treating it as almost a probing, how far would we go, how much would we do.
