In 1950, the United States extended an overture to Pakistan by inviting Prime Minister Khan for an official state visit. As the USSR had rebuffed capitalist Pakistan and aligned itself with Pakistan's rivals, the country's policy crafters found that maintaining friendly relations with both superpowers was impossible. Prime Minister Khan accepted the American invitation and paid an official 23-day state visit to the United States beginning on May 3, 1950. The event was highly politicized in Pakistan, and outraged the country's leftists, and was seen as the seminal event that leads to warm diplomatic ties for several decades. However, it is alleged that during PM Khan's first visit to the US, president Truman requested Pakistan's premier to let the CIA formulate a base in Pakistan, strictly to keep an eye on the activities of Soviet Union—a request which was not granted by Khan.
