In 2011 Biden delivered the keynote address at the Atlantic Council’s distinguished leadership awards. He did so again in 2014 at its “Toward A Europe Whole and Free” conference, which was dedicated to expanding NATO’s influence and countering “Russian aggression.” Speakers like [[Zbigniew Brzezinski]], a former U.S. [[national security adviser]], sniped at Barack Obama for an insufficiently bellicose posture toward Russia, while former Secretary of State [[Madeleine Albright]] fretted over polls showing low public support for U.S. [[interventionism]] overseas. Biden emphasized the need to power [[Europe]] with non-Russian sources of natural gas. This provided a prime opportunity to Ukrainian suppliers like Burisma and U.S. energy titans. Many of these energy companies, from [[Chevron]] to Noble Energy, also happen to be top donors to the Atlantic Council.
