Pentagon: Europe faces terrorism threats and aggression from Russia
For the first time in a "very long time," the United States and its allies are facing the "very distinct threats" of a conventional state threat from Russia, Dempsey said, and the unconventional threat of terrorism from extremists.
"Where Italy sits, strategically, you're faced with the reality of dealing with both of those threats, as we are; I think that draws us closer together," he said.
There is concern, both sides noted, that foreign fighters could be moving through Italy's and NATO's southern flanks. Close to 170,000 refugees have come through Italy's shores in the past year.
Dempsey said the approach in dealing with extremism should consider the swath of countries from the Middle East to Africa, where ISIL and other terrorist groups operate.
"Looking at it one country at a time is not the answer," he said, noting he and other allies will discuss the issue Wednesday and Thursday in NATO meetings in Brussels.
He said Russian aggression will also be a topic in the NATO talks.
