INTRODUCTION

In the fall of 1949, the American Congress passed the Mutual Defence Assistance Act that led to a programme commonly known as “security assistance”. In accordance with this act (and later revisions), the United States came to export almost US$500 billion in arms and related military services from 1950 to 2001. The transfer of military equipment to allies and friendly states has remained a consistent feature of U.S. foreign policy, although there was a significant change in how arms were supplied. The United States provided arms free of charge in the beginning, but gradually began to demand payment. In other words, there was a shift from military aid to military sales (the aid/sale transformation). The transition was remarkable: in 1950, for example, only 4 per cent of the total agreements on weapons exports were sales; but in 1984, military sales accounted for more than 90 per cent of all U.S. arms exports. Even after the Cold War, this percentage was never lower than 63 per cent. The purpose of this study is to develop a consistent explanation of this increase in the percentage of arms sales, after which the data is tested on the case of U.S. arms exports to East Asia.

This involves two important features. First, arms transfer is an “international” activity between at least two states or international actors. In other words, arms transfer involves cooperation between states, and requires a supplier to export arms and a recipient to import them. If either the supplier or the recipient is not capable or not willing to cooperate, no arms transfer can occur.

This chapter contends that U.S. arms transfers cannot be adequately studied by examining the supplier side alone. The supplier and the recipient are equally important in understanding the pattern of U.S. arms transfer.
