Since the early 1990s, the U.S. arms industry's income from Saudi purchases alone has been particularly sizable. For instance, of the $10 billion in 2016 U.S. arms exports, Saudi purchases comprised 20% of total exports. In order to sustain exports of such quantity to Saudi Arabia, the U.S. has consistently supported notions of regional insecurity within the Saudi monarchical regime, especially in its perception of an Iranian threat. This situation entails non-reciprocal sales of U.S. defense equipment to the Saudi government, with the latter as the sole purchaser. Therefore, if sales with Saudi Arabia ceased, income to U.S. firms from arms dealing would shrink, affecting profits from the top down. For the Kingdom, its arms cache would merely stop expanding, at least at the rate the U.S. enables. U.S. interest in Saudi arms purchases fosters a need that spurs the seemingly-natural trade cycle; the U.S. needs Saudi Arabia to continue to think it needs U.S. defense equipment. What is called a security dependency is actually pragmatic discourse for American economic interest in a Saudi appetite for war.
