Even at the best of times, Pakistan-US relations have been marred by mistrust.
Historically, the United States has gravitated towards Pakistan when it has needed to in terms of its strategic interests. In the late 1950’s, for example, the US not only supported a military dictator (General Ayub Khan) but also operated airbases inside Pakistan to be used against the growing military power of the Russia.
In 1962 a U2 long range reconnaissance aircraft took off from Badaber, on the outskirts of Peshawar, for a spying mission over Russia. The plane was due to fly all the way to Norway, but was shot down by the Russians, who then triumphantly put the pilot, Gary Powers, on display to the world.
