Pakistan received over a billion dollars in US military aid between 1954 and 1965. This aid greatly enhanced Pakistan's defence capability as new equipment and weapons were brought into the armed forces, new military bases were created, existing ones were expanded and upgraded, and two new Corps commands were formed. Shahid M Amin, who had served in the Pakistani foreign service, wrote, "It is also a fact, that these pacts did undoubtedly secure very substantial US military and economic assistance for Pakistan in its nascent years and significantly strengthened it in facing India, as seen in the 1965 war."
