I personally found Donald Trump's praise for Vladimir Putin troubling or even chilling, frankly. In a room full of military veterans, to be effusing about his great leadership and how strong he is and how popular he is, while disrespecting the American president and American generals, I don't know. That was, I think, not just troubling to me, but to a lot of listeners and I think, frankly, to a lot of Republican listeners as well.

One even tries to figure out why Donald Trump is so admiring of a leader who has cracked down on journalists and is suspected of using even violence, cracked down on civil society, ruling with an iron fist within Russia. To look with admiration on that sort of domestic leadership, I think is just really inconsistent with American values.

I was going to the heart of this matter, which is, the issue of whether Europeans should contribute more to NATO, I think, is a matter of consensus. I think Secretary Hillary Clinton believes that, and a series of U.S. presidents and secretaries of defense and state have urged our European partners.

Secretary Hillary Clinton for four years was part of a policy of resetting Russian relations with Russia in our interests.

Donald Trump said that he thinks he can get along very, very well with Vladimir Putin and have very, very good relations with Russia. I'm sure he can, if he is willing to turn away from our NATO allies and reconsider whether Eastern Ukraine is really part of the country, and do whatever he can to accommodate Mr. Putin's views.

I'm sure that Donald Trump's praise would lead to good relations with Vladimir Putin. But I think that's not what the American people expect from our foreign policy.
