Russia's invasion of Ukraine has sharpened NATO's focus and is accelerating difficult and timely discussions regarding NATO unity and NATO members' defense spending. Far from creating fissures within NATO or weakening the alliance as Putin might have hoped, Russia's unprovoked aggression has unified the West and provided the necessary impetus to spur additional military spending within NATO countries. Most striking has been Germany's recent announcement that it would increase defense spending to over 2% of GDP a year. This is a welcome change within NATO and one for which the U.S. has long advocated.
