Final answer:
Luxembourg is the country bordered by Belgium to the west, Germany to the east, and France to the south. It has historical significance due to its location and role during the World Wars and is part of the Benelux Union.
Step-by-step explanation:
The country bordered by Belgium to the west, Germany to the east, and France to the south is Luxembourg. Luxembourg is a small nation that played a significant role in the history of Western Europe, particularly during both World Wars. During World War I, Germany's military strategy involved an attempt to cross Belgium to attack France, which brought significant attention to Belgium's strategic location and its desire to maintain neutrality. Meanwhile, in World War II, Germany advanced westward, invading neutral countries in the region, including Luxembourg, to circumvent France's Maginot Line.
Luxembourg is part of the Benelux countries, along with Belgium and the Netherlands, forming a union that is situated in the west of Central Europe. The region's historical significance is also underlined by the fact that after World War II, Luxembourg was among the Western-aligned countries, and during the Cold War era, Germany was divided into East and West Germany, with Luxembourg neighboring what was then known as West Germany.
