Finland became the newest member of NATO today, as the country's flag - a blue cross on a white background - was raised over the defense alliance's headquarters in Brussels.
At the ceremony, NATO Secretary-General Jens Stoltenberg announced, "For almost 75 years, this great alliance has shielded our nations and continues to do so today. But war has returned to Europe and Finland has decided to join NATO and be part of the world's most successful alliance."
