NATO will respond “with full force” if Russia attacks any of the alliance’s territories, White House national security adviser Jake Sullivan said on March 13.

The incident would trigger NATO’s Article 5, which states that an attack on one NATO nation would be considered an attack on all allies, he told CBS News. Sullivan didn’t say how severe the attack would have to be to trigger the provision.
