Diplomatic expulsion is the act of a country severing diplomatic ties with another country, recalling its ambassador, and closing its embassy in that country.

Diplomatic expulsion can be used as a response to a variety of actions by another country, including espionage, terrorism, human rights abuses, and other serious violations of international law.

Diplomatic expulsion can have a number of consequences, including the inability of the two countries to communicate directly, trade with each other, or travel to each other's countries.

Espionage, or the act of spying, is the most common reason for diplomatic expulsion.

Diplomatic expulsion can have a number of potential risks, including a further deterioration of relations between the two countries, making it more difficult to resolve disputes between the two countries, and increasing the risk of conflict between the two countries.

Diplomatic expulsion can have a number of potential benefits, including sending a strong message of disapproval to the other country, deterring the other country from taking further actions that could harm the relationship between the two countries, and helping to protect the interests of the country that is expelling the diplomats.

There are a number of alternatives to diplomatic expulsion, including issuing a diplomatic protest, imposing economic sanctions, and suspending diplomatic relations.

When deciding whether or not to expel diplomats, countries consider a number of factors, including the severity of the offense that led to the expulsion, the relationship between the two countries, and the potential consequences of the expulsion.

The United Nations does not have a formal role in diplomatic expulsion. However, the United Nations can mediate between the two countries to try to resolve the dispute, or it can impose sanctions on the country that is expelling the diplomats.
