ABC News Radio cites the Atlantic Council for hosting Secretary of State John Kerry at its two-day "Towards a Europe Whole and Free" conference:

Kerry, who was speaking at the Atlantic Council’s conference commemorating the NATO alliance, suggested he was also regretful to see Russia behave this way.

“I say this was a certain element of sorrow because of all of the effort and energy that has been expended to try to create a structure by which we would behave, all of us, differently, representing the best hopes and aspirations of all people on the face of this planet,” he said.
