In politics, there are key terms that are used to explain the relationship among events that are going on. Actors are the key people who are involved in a political event. Interactions are the starting points in politics. The group of procedures to follow are considered the institutions. The key people in politics or actors really want three main things. Those are authority over safety, financial stability and realistic objectives. In order to fulfil these things, the actors get together or collaborate to make sure these things get done. These are known as their interests. Sometimes, bargaining occurs in order to achieve these objectives.
