In the midst of bitter bailout negotiations between Greece and Europe, warnings proliferated of a possible Greek fifth column. The European Union and even NATO would collapse should Athens turn toward Russia. It is one of the stranger paranoid fantasies driving U.S. foreign policy.
For five years Athens has been arguing with its European neighbors over debts and reform. The issue doesn't much concern the United States. A European economic crisis would be bad for America, but Grexit is not likely to set off such a cataclysm.
Nevertheless, some analysts speculated that Athens might fall out of the European Union and NATO as well as the eurozone, resulting in geopolitical catastrophe. Thus, the U.S. should insist that Europe pay off Greece. Despite an apparent bailout agreement, another crisis seems inevitable, in which case the specter of a Greek Trojan Horse likely will reemerge.
