In a significant geopolitical move, Saudi Arabia, Pakistan, and Turkiye have forged a trilateral defense pact. Signed in Mecca on Friday, the agreement stipulates that any external armed attack on any of the three countries will be considered an attack on all. The formation of this alliance comes amidst ongoing tensions between the United States and Iran, with no final deal yet reached to end their conflict. Iran's response has been relatively subdued, with officials focusing on aspects of regional cooperation and the perceived diminishing role of the US. However, concerns linger in Tehran regarding potential strengthening of Saudi Arabia's deterrence and possible coordinated pressure on Iran in Yemen, Iraq, and economically through Turkiye and Pakistan. The timing of the agreement is significant, following months of war during which Saudi Arabia faced attacks from Iran-aligned groups. While Iran has not issued a formal statement about the pact, officials have indicated that they view it within the context of a diminishing direct US presence in the region. Experts suggest that the alliance could mark the beginning of a new regional security order and the end of the prevailing security paradigm in West Asia. However, decision-makers in Iran do not immediately feel threatened by the pact, especially since they have maintained cordial relations with both Pakistan and Turkiye even under trying circumstances.
