The Grand Alliance was not a formal alliance, but rather a loose coalition of countries with a common interest in defeating the Axis Powers. The Grand Alliance was held together by a shared commitment to democracy and freedom, and a determination to resist aggression.
The Grand Alliance played a crucial role in the defeat of the Axis Powers. The combined strength of the Allies, and their cooperation, enabled them to overcome the challenges posed by the Axis, and to ultimately achieve victory in World War II.
