The Quadrilateral Security Dialogue (Quad or QSD), a proposed multilateral platform consisting of the United States (US), India, Japan and Australia intended to underpin a future Asia-Pacific order, has the potential to significantly impact Pakistan‟s international standing. As an important regional actor, Pakistan‟s responses to such a platform will be influential. This article discusses possible ways Pakistan is likely to perceive the Quad and its consequences. It analyses the nature of the Quad, Pakistan‟s foreign policy and current geopolitical trends to provide a framework for discussion. It then outlines two potential forms the Quad may take, aggressive and cooperative, and explores Pakistan‟s likely perceptions and responses. It finds that in case of an aggressive Quad, Pakistan will resist pressure and seek external support which may trigger greater strategic competition, whereas it may be willing to adopt a balanced foreign policy in the case of a cooperative Quad. These findings demonstrate the importance of considering such long-term implications at a time when other concerns are driving international engagement with Pakistan.
