The months of protests in Ukraine that led to the ousting of president Viktor Yanukovych were just one example of "people power" in recent months.
Such protests were "a reflection of this incredible yearning for modernity, for change, for choice, for empowerment of individuals that is moving across the world, and in many cases moving a lot faster than political leadership is either aware of or able to respond to," the top US diplomat told a small group of reporters.
"A democracy is not defined solely by an election," the top US diplomat argued.
"You can have a democratically elected government, but you don't have democratically-instituted reforms that actually give you a democracy, a full, practising, functioning democracy," Kerry said.

Yanukovych was elected in close presidential elections in 2010 in the former Soviet satellite.
He narrowly defeated his 2004 Orange Revolution co-leader Yulia Tymoshenko, who he later threw behind bars.
