Which country from the east African community received the lowest military assistance from US ???

As an AI language model, I don't have real-time data. However, historically, Burundi has received the lowest military assistance from the United States among the East African Community countries. Burundi has had a troubled political and security situation, which has limited its military cooperation with the US compared to other countries in the region. Please note that this information may have changed, and it is always best to refer to the latest official sources for the most accurate and up-to-date information.
