Hamid Karzai during the interim, transitional and elective government (two courses) from 2002 to 2014, was the Afghanistan president that, in terms of increasing communication channels across the region and the world, provided widespread assistance to the international community and the development of a unique democratic era behind. Afghanistan’s changing foreign policy during Karzai’s time has made foreign policy management and decision-making more important than ever, and from this perspective the question of the research has been formed; what is the influential component of foreign policy decisions during the reign of Hamid Karzai? the model of James N. Rosenau’s Linkage model was chosen to analyze Karzai’s foreign policy in order to answer this question.According to this model, in countries such as Afghanistan, which are politically open and economically developing, respectively the individual components, international system, role variable, society and government have the most influence in foreign policy decisions of the country. Using this model, the research findings showed that during the study period, although the individual component and the international system had the most impact on foreign policy decisions in the country, but contrary to the Rosenau’s Linkage model, Afghanistan’s foreign policy analysis in other cases with the model And the component of the role and society is lower than the role of government in foreign policy decision-making. Research findings are an appropriate response to the failure to take advantage of opportunities and control threats in foreign policy of the country.
