The New York Times writes about it.

"The most costly conflict in Europe since the Cold War has pushed the North Atlantic Treaty Organization into a full-scale effort to become a viable military alliance," the report said.

According to the newspaper, these changes were "transformative for an organization that has been dormant for years."

On April 4, Finland officially joined the North Atlantic Alliance.

Russian Deputy Foreign Minister Alexander Grushko said that Russia has already begun to develop retaliatory measures to stop possible threats due to Finland's accession to the North Atlantic Alliance.

As reported by the commander of the air defense-missile defense forces, Deputy Commander-in-Chief of the Aerospace Forces, Lieutenant-General Andrei Dyomin, the Russian air defense forces have begun to work out issues on protecting the northwestern border against the background of NATO expansion due to Finland's accession to the alliance.
