What country has gained the most territory since its independence?
Oh, I see. What about the United States, has it gained or lost territory over the years?
The United States has gained significant territory over the years, particularly through westward expansion in the 19th century. It also acquired Alaska from Russia in 1867 and Hawaii as a territory in 1898. However, it has also lost territory in the past, particularly during the Mexican-American War of 1846-1848, when it gained land from Mexico but also ceded territory to it.
