Which country or nation is America’s oldest ally?

Answer:

France is most certainly America’s oldest ally as they directly assisted in the American Revolutionary War and supplied large amounts of weapons and ammunition to the revolutionary troops. They also granted large areas of land to the United States in the Louisiana Purchase and have aided the United States in almost every major conflict of the modern era, particularly the First and Second World Wars. The Statue of Liberty is a gift from the French as a present to commemorate the American Revolution and ties between both nations have always been strong.
