The Grand Duchy of Luxembourg is a small landlocked parliamentary democracy and constitutional monarchy in Western Europe. It is bordered by France, Germany, and Belgium. Consequently, Luxembourg was invaded by Germany during both World Wars, and was actually annexed by the Greater German Reich during World War II. It was liberated in 1945.
Luxembourg is a founding member of the European Union, NATO, and several other multinational organizations.
Luxembourg was a NATO member when World War III began. By July 1951, there was a very real possibility that the SovietRed Army and its allies would cross overwhelmed West Germany and invade Luxembourg. In response, the United States dropped several atomic bombs on the Soviets' forward positions in West Germany, destroying a sizable chunk of their military and forcing a retreat from Luxembourg.
