The fall of the Ba'athist regime marked the beginning of new developments in the Iraqi political arena, which made the political and social climate of the country ready to accept new discourses. In this context, various regional and supra-regional powers, especially Iran, the United States, Turkey and Saudi Arabia, began new efforts to strengthen their media and discourse in Iraqi public opinion. In this context, media diplomacy can be considered as the least expensive and most effective tool that has the capacity to positively influence the public opinion of other countries in order to achieve national interests. In other words, media diplomacy is one of the tools that can improve the soft power indicators of any country. The Islamic Republic of Iran has made great efforts in recent years to use this tool against neighboring countries, especially Iraq. Accordingly, the main question that the present article addresses is what are the characteristics of the media diplomacy and discourse strategy of the Islamic Republic of Iran towards Iraq in the post-Saddam period and what trends and developments has it experienced? Using comparative and descriptive-analytical methods, the present article hypothesizes that the strategy of media diplomacy and discourse of the Islamic Republic of Iran in Iraq is based on the quantitative and qualitative development of audio-visual media with the aim of promoting soft power indicators.
