The planting of false stories is nothing new; the Soviet Union devoted considerable resources to that during the ideological battles of the Cold War.

President Barack Obama said he wouldn’t decide whether to supply weapons to Ukraine until European leaders exhaust one last diplomatic effort to resolve the conflict there, setting aside for now trans-Atlantic differences on the best way to get Russia to relent.  Mr. Obama announced his decision after a White House meeting Monday with German Chancellor Angela Merkel that followed days of sometimes testy exchanges between U.S. and German officials.

It was -3 degrees in Munich over the weekend and, inside the 51st Security Conference, there was an unmistakable cold war chill.  For three days the Bayerischer Hof hotel was a security and diplomatic lockdown as western leaders clashed with Russian counterparts over the way into – and out of – the Ukraine crisis. Delegates arrived in glum agreement over the risks posed by the conflict, and departed after heated disagreements over whether military might or diplomatic skill could save the day.
