The "stick and carrot" policy means simultaneous use of the threat (stick) and encouragement (carrot) to manage the behavior of countries or groups. This approach is especially used in international policy and in relations with countries such as Iran. In this policy, the stick acts as a tool of punishment and the carrot as a tool of encouragement. In some cases, enemies try to deceive the target country by making incentive promises alongside threats.This is a costly policy for the national security of any country, which itself can be considered as a necessity and importance in preventing crimes against national security. With a descriptive and analytical look and a documented and library approach, it can be said that this approach usually involves economic or security proposals, which at the same time are accompanied by military or sanctions threats. These types of policies usually lead to distrust among countries and can disrupt the peace process. Also, creating a sense of despair and division in the target community can have negative effects on the internal stability of that country.As a result, understanding the precise policy of hammers and carrots and the preventive measures of enemies can help countries act more vigilantly against threats and prevent security crises.
