Conclusion
Merica's withdrawal from Afghanistan is an important component of Washington's return to the rebalancing strategy, a strategy that implies the mobilization of resources in new vital areas. The redistribution of power in the international system has forced America to redefine the source of threat (from terrorism to hegemonic powers) and the center of threat (mainly) from West Asia to East Asia. China's rise over the past three decades has become the main challenge to America's hegemony in Asia-Pacific. In addition, Russia due to its strategic expansionism in Europe and Iran due to its regional and nuclear activism in the Middle East are considered challenges to American hegemony. The main reason and goal that motivated America to withdraw from Afghanistan is to confront its hegemonic position with the increasing influence of China as the highest priority, followed by Russia and finally Iran. The aim of the article was to analyze the withdrawal of America from Afghanistan in the framework of rebalancing in the geopolitics of West Asia.
