The United States, a vast and diverse country, is situated in North America and is bordered by two sovereign nations. These countries are Canada and Mexico. The United States shares the longest international border in the world with Canada, which stretches from the Atlantic Ocean to the Pacific Ocean, and it's the fifth longest land border globally. This border is unique in that it is not fortified and is considered one of the most peaceful and secure borders in the world.

To the north, the Canada-United States border is divided into two sections: the border with the contiguous United States and the border with Alaska. The contiguous United States shares a border with Canada that extends for approximately 4,000 miles (6,400 kilometers) and is marked by various natural features such as rivers and lakes. The border with Alaska, known as the Alaska Panhandle, is to the east and is much shorter, spanning approximately 1,538 miles (2,475 kilometers).

On the southern front, the Mexico-United States border runs along the Rio Grande and Colorado River, extending from the Pacific Ocean to the Gulf of Mexico. This border is approximately 1,954 miles (3,145 kilometers) long and is marked by a combination of natural and man-made features. It is a significant point of trade, migration, and cultural exchange between the two countries.

Both borders are subject to international treaties and agreements that govern their management and security. The United States has a complex relationship with both of its neighbors, characterized by cooperation in trade, security, and environmental conservation, as well as occasional disputes over issues such as immigration and resource management.

The border with Canada is one of the most significant bilateral relationships globally, with deep economic, cultural, and political ties. The two countries are part of the same trade blocs, such as the North American Free Trade Agreement (NAFTA), which has been superseded by the United States-Mexico-Canada Agreement (USMCA). This agreement further strengthens the economic integration and cooperation between the three countries.

The border with Mexico is also of great importance, with a long history of interaction. The United States and Mexico have a vibrant trade relationship, and Mexico is one of the United States' largest trading partners. There are also numerous cultural exchanges and a significant Mexican-American community in the United States that contributes to the cultural diversity of the country.

In conclusion, the two countries that border the United States are Canada and Mexico. These borders are not just lines on a map but represent complex and multifaceted relationships that are vital to the United States' economic, security, and cultural interests.
