Investigate Pakistan's role in ensuring Iran's national security

The Islamic Republics of Iran and Pakistan are two neighboring countries that have many commonalities and are, algebraically, side by side with a relatively common regional destiny. In this regard, in this article, using a descriptive-analytical method and using the theoretical framework of the Copenhagen School, we seek to answer the question that what role does Pakistan play in ensuring Iran's national security? The hypothesis put forward is that Pakistan plays an important role in supporting Taliban terrorism, developing the port of Gwadar versus the port of Chabahar, supporting NATO and US presence in the region, separatists in Balochistan, Pakistan, and drug trafficking. Iran's national security and in this regard, Iran's support for Kabul during the Kabul-Islamabad dispute has weakened Iran's national security on the part of Pakistan. The findings of this study show that therefore the conflicting interests of the Pakistani government with Iran, facilitate The presence of US and NATO troops in the region has been and the threats posed by drug trafficking and transit and the issue of Afghanistan have been the result of cooperation between the government and the Pakistani community against Iran's national security.
