Diplomacy is the act of dealing with other nations, usually through negotiation and discussion. Diplomacy involves meetings between political leaders, sending diplomatic messages, and making public statements about the relationship between countries. The American president, for example, often hosts leaders and chief diplomats of other nations at the White House in order to discuss a variety of issues. Most diplomacy occurs behind the scenes as officials hold secret negotiations or meet privately to discuss key issues.
Approaches to Diplomacy
States generally pursue diplomacy in one of three ways:
Unilaterally: The states acts alone, without the assistance or consent of any other state.Bilaterally: The state works in conjunction with another state.Multilaterally: The state works in conjunction with several other states.
There are pros and cons to each of these three approaches. Acting unilaterally, for example, allows a state to do what it wants without compromise, but it must also bear all the costs itself. Acting with allies, on the other hand, allows a state to maintain good relations and to share the diplomatic burden, but this often requires compromise
