As president, I will stand up to the great human rights tests of our time - in China, Russia, and the Middle East. We must send a signal to our allies and adversaries that America is back in the leadership business.

Everything Bill Clinton has done is fair game. He's a former president. I just don't think that is the most effective way to beat Hillary Clinton, because while all that was going on there were a lot of women who felt for whatever reason great sympathy for Hillary Clinton. Look, if my husband were doing that, I would have left him. I would not have behaved the way Hillary Clinton did.

One of the things I would immediately do [as Commander in Chief ], in addition to defeating them here at home, is bring back the warrior class - Petraeus, McChrystal, Mattis, Keane, Flynn. Every single one of these generals I know. Every one was retired early because they told President [Barack] Obama things that he didn't want to hear.

We must work with the Australians, the South Koreans, the Japanese and the Filipinos to contain China. And then we must ask for their support and their help with North Korea. Because believe it or not, China is as concerned about Kim Jong-Un as we are.

When Hillary Clinton talks about adding more restrictions and complexity to our financial system, as she did in her economic policy speech, it shows how clueless she is about how the economy actually works.

I think more to the point, these pivotal times means something other than a politician. I understand the economy. I understand the world. I have a lot of foreign policy experience. I understand bureaucracies. I understand technology, and I understand leadership.

The world is a more tragic and dangerous place when American isn't leading and, under this president, we have not been leading.
