The geopolitical study of Pakistan in the field of rivalry with the Islamic Republic of Iran in the Yemeni Crisis is the main subject of the present study. Using a descriptive-analytical method, this research seeks to answer the question of how far the geopolitical challenges and conflicts between Pakistan and Iran affect the crisis in Yemen. The hypothesis also suggests that geopolitical challenges and Pakistan's incompatible rivalries have increased Saudi co-operation with the country in the Yemeni crisis.

Since the start of the Saudi invasion of Yemen, the issue of Pakistan's entry into the war has also been raised, but Pakistan has never been able to effectively enter this war due to the presence of Iran on one side of this front and Israel as one of the allies of India on the other side of the front.
