What is traditionally known as the world's longest undefended border?

The border between Canada and Mexico
The border between Canada and the USA
The border between France and Germany
The border between Australia and New Zealand

The correct answer is: The border between Canada and the USA

The world's longest undefended border is the border between Canada and the USA. This is because the two countries have a long history of political and economic cooperation, and have a strong relationship with each other. Additionally, the vast majority of the border is made up of natural barriers, such as rivers and lakes, making it difficult to cross illegally. The other options listed are incorrect as the border between Canada and Mexico is defended by both countries, the border between France and Germany is protected by various military and police forces, and the border between Australia and New Zealand has a strong military presence due to their shared defense agreement.
