RTE News cites the Atlantic Council for hosting Secretary of State John Kerry at its two-day conference, “Towards a Europe Whole and Free:”
Mr Kerry described the events in Ukraine as a “wake-up call” to NATO allies.
He said the crisis puts “our entire model of global leadership” at stake.
Mr Kerry was speaking at an event about US-Europe ties at the Atlantic Council think-tank and told those gathered that what “Russia’s actions in Ukraine tell us is that today President Putin is playing by a different set of rules”.
