There comes a time, in the history of Nations when fear and forgetfulness cause a nation to hesitate, to waver and perhaps even to succumb. When that time comes those who love liberty must rise to the occasion. Will you? Will you lovers of liberty, will you rise to the occasion?

America's not the world's policeman. Terrible things happen across the globe and it is beyond our means to right every wrong. But when, with modest effort and risk, we can stop children from being gassed to death and thereby make our own children safer over the long run, I believe we should act.

My grandfather would live to see his children become doctors and ministers, accounts and professors.

I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.

The idea of foreign policy realism, I think, fits more neatly with President Trump. And with John McCain, the neoconservative label of let's make the world safe for democracy and we're going to topple every regime hasn't worked.

I think that most manufacturing and mining should be under the purview of state authorities.

2007 was a long time ago, and events do change over long periods of time.
