There are at least five benefits to US arms sales and aid transfers: (1) they can serve specific US national security objectives, such as defeating the USSR in Afghanistan and thus helping win the Cold War; (2) arms sales help to lower the cost of weapons purchased by the US taxpayer by spreading R&D costs over a larger production run; (3) the US gains supplier leverage over countries we equip because they remain dependent on the US for spares, training, and support; (4) countries that we help arm tend to become more firmly attached to the US as allies; and (5), the availability of reliable, potent weapons from the US helps to diminish the incentives for purchases from other suppliers like Russia, China, and Europe and for indigenous weapons development and proliferation.
