Diplomacy is the process of strengthening a state, nation or organisation in relation to other states through the advancement of interests without resorting to coercion and preferably without offending or antagonising others. It is also the practice of negotiating with other countries to settle disputes. In this way, it paves the way to peaceful relations between nations and other sites of power and influence, including multinational corporations, religious organisations and even terrorist groups.

The main task of the diplomat is to be a master at communication, both in person and in writing. They must be able to convey their point of view, but they also have to listen well and respond to their interlocutors. They must also be able to adapt to a constantly changing environment and remain resilient under pressure.

A good diplomat knows how to avoid offending their colleagues by using a light tone of voice and relaxed body language. They also know how to keep their thoughts organised by writing notes and not speaking too fast. Diplomats are also very observant and notice the little things that can make or break a conversation, such as if someone has a pen dangling from their ear or is wearing jeans and sneakers.

Unlike politics and business, which are often based on short-term gains and profits, diplomacy is a long-term endeavour that requires integrity and trust. This is why some of the greatest diplomats have been known to get away with breaking rules from time to time.
