How many countries are separated by the world's smallest border?

How many nations are separated by the shortest border in the world?

One of the meanings of the word border is that of boundary between two nations. The smaller the nation, of course, the smaller that country's border with another nation will be.

The tiny nation of Vatican City, for example, has a border of about 4 kilometers, and the colony of Gibraltar, on the Mediterranean, has a border of only 1,500 meters.

Curiously, the shortest border in the world is the boundary between some of Africa's largest nations, not just two, but four! This border between 4 nations is where Zambia, Zimbabwe, Botswana and Namibia meet.

If you were there, you could put one foot in each of the nations of Namibia and Zimbabwe, and put one hand in Zambia and the other in Botswana, and you would be in all four countries at the same time!
