An ambassador is an official envoy, especially a highest ranking diplomat who represents a state and is usually accredited to another sovereign state, or to an international organization as the resident representative of their own government or sovereign or appointed for a special and often temporary diplomatic assignment.[1] The word is also often used more liberally for persons who are known, without national appointment, to represent certain professions, activities and fields of endeavor.
Protect citizens
Support prosperity
Work for peace
One of the cornerstones of foreign diplomatic missions is to work for peace. This task can grow into a fight against international terrorism, the drug trade, international bribery, and human trafficking. Ambassadors help stop these acts, helping people across the globe. These activities are important and sensitive and are usually carried out in coordination with the Defense Ministry of the state (or the Defense Department in the U.S.) and the head of the nation.
