In today’s globalized world, states adopt foreign policy according to their needs and interests. They define their role keeping in view their explicit goals in international affairs and describe their position through certain facts and factors. Moreover, each state has its own priorities and proclivities in policy-making, which are rooted in its territorial location, historical traditions and political culture. In the cold war years, Pakistan’s security concerns led it to search and test various options. The rival surrounding and the threat perception forced it to pursue defense-oriented policies. From the early days of independence, threats were being faced even to the very existence of the country. The initial clashes with India occupied central place in determining the dimension of foreign policy and complete range of outward ties circulated around it. The objective of the paper is to analyze the foreign policy of Pakistan, viewing the setting of the cold war, which determined its behavior and direction. Pakistan had to join the defense alliances to secure its position against hostile environment. However, it has to opt for non-alignment and nuclearization. Here is the question about those circumstances, which compel Pakistan to pick the specific options, paying a high cost for security. Reviewing available literature and viewing the empirical evidences, the paper has hypothesized that in quest of security, weaker states have been forced by the powerful states to pursue policies under their instruction, which are directly or indirectly secure the interests of powerful actors with rare chances of free options. It is recommended that in search of security, Pakistan has to determine its own direction, without compromising on its policies as the rational choice minimize the loss.
