Stoltenberg says NATO is most powerful defense alliance of all times

NATO is the most powerful defense alliance of all time, NATO Secretary General Jens Stoltenberg said.

However, he drew attention to the fact that Russia increasingly mentions nuclear weapons as a part of its defense strategy. "Our response is proportional and complies with international treaties. We have increased the readiness of our forces. We have strengthened our military presence on the eastern borders of the alliance," Gazeta.ru cited him as saying.

"NATO never sleeps," the secretary general noted, saying that the alliance was called a sleeping giant.
