In an interview with the Serbian newspaper Politika, the Secretary-General of NATO Jens Stoltenberg said that "aggressive policy" of Russia is the main threat to NATO.
He also noted that among other threats, there are the activities of hackers, terrorism, and instability in the Middle East and North Africa.
The Secretary-General called the overall security situation "the most unforeseen" in many years, stressing the importance of NATO in these conditions.
"The strong ties between Europe and North America have made NATO the strongest Alliance in history. The fact that we will soon accept Northern Macedonia as the 30th member shows that NATO is a successful Alliance," he said.
The Secretary-General said that one of the priorities of the Alliance is stability in the Serbian province of Kosovo and Metohija, where conflict with Serbia has escalated.
