The best reason why the United States provides military aid to other countries is: To protect an established alliance.
<h3>What is an Alliance?</h3>
An Alliance is a forged relationship between individuals, groups, communities, and even countries for mutual benefits. They come together to achieve a common goal and purpose.
When the United States provides military aid to countries, they hope to protect the already forged alliance with the country. They have an agreement and it must be fulfilled by both parties or countries.
