You have to guess the country's shortest land border with another country. Island Nations and countries with one land border (such as Denmark or Ireland) are NOT counted.
The answers have to be of fully-recognized countries. Western Sahara, in this instance, is regarded as part of Morocco.
The answers must be of LAND borders, so no bodies of water such as oceans or lakes.
Overseas land borders count as land borders for the original country (E.G: French Guiana is counted as part of France)
