Secretary of State Marco Rubio was in Athens on Oct. 7, the second stop on a three-nation tour of NATO’s periphery that began in Iceland and ends in Portugal. He announced that the United States and Greece, which he called a “strong and model NATO ally,” would launch new counterterrorism information-sharing between their law enforcement agencies, Defense News reported. He said Greece is particularly exposed to the threats of mass migration and human trafficking.

“As part of our efforts to combat these common threats to our nations, we’re proud to announce a new memorandum of understanding establishing a joint security program to strengthen the counterterrorism information sharing between our respective law enforcement agencies,” Rubio told reporters alongside Greek Foreign Minister George Gerapetritis.
