🕊️ Berlin Blockade Ends
The Soviet blockade of Berlin ends with the re-opening of access routes to Berlin. The airlift continues until September, in case the Soviets re-establish the blockade. Brune argues, "Moscow realized the blockade had not been successful – it had drawn the Western powers closer together rather than dividing them. Finally, Western countermeasures had inflicted considerable damage on the economic life of East Germany and the other Soviet satellites."⟶
