D-Day marks the historic June 6, 1944, Allied invasion of Normandy, a pivotal turning point in World War II that paved the way for the liberation of Western Europe from Nazi control. Today, the anniversary serves as a solemn occasion for global leaders to honor the bravery of the veterans who fought for freedom, while drawing critical parallels between the defense of democracy during the Second World War and contemporary geopolitical struggles, such as the ongoing conflict in Ukraine.
