The Berlin blockade, which lasted for almost a year, was a Soviet political failure from start to finish. It failed to make west Berlin destitute; a US and British air-bridge provided enough supplies to keep the western sectors going. On some days aircraft landed at Tempelhof Airport at three minute intervals. Moscow did not take the risk of ordering them to be shot down. But worse for Stalin: the long-drawn-out standoff confirmed even to those Germans who had previously been in doubt that the Soviet Union could not be a vehicle for their betterment. The perception was that Stalin was trying to starve the Berliners, while the Americans were trying to save them.
