You don`t have to be foreign policy expert to succeed as president, but you have to have ice water for blood.

Politics should seize the imagination.

In a sense, whites who were always sort of the unthinking majority who didn't think of themselves necessarily as one among many interest groups but is simply the dominant group, now as whites become - are close to becoming a minority of Americans, are becoming a political interest group. And that's what Donald Trump is playing to. And it's a really dangerous, volatile game.

It used to be that the working class, broadly speaking - Americans who worked with their hands, who worked in factories, who were not in management - were an interest group, a political interest group. And their main spokespersons were the Democrats. Their platform was the Democratic Party. And that began to change after the 1960s. Not for black or other working class Americans, but for white working class.

I would caution anyone who thinks the solution is to get out to realize that Iraq will be our problem, whether we're there or not, for years to come. It will not be Vietnam; it will not let us go home and lick our wounds.

The biggest issue for me is whether large numbers of Americans can begin to think that government can actually help make the country a fairer place. And that's partly a matter of policies that achieve results in terms of reducing inequality and raising middle-class and working-class incomes, which have been flat for decades. But it's also symbolic and rhetorical, it's whether Hillary Clinton can - or whoever's president - can persuade Americans that it's happening and that they can begin to trust their elected officials a little bit more and their institutions of government a little bit more.

It's kind of funny to read the work of ex-Marines and soldiers because what they said to me as a reporter was only a fraction of what they were thinking and feeling and saying to one another.
