Yes, the reasoning being was that there were two options to make the Japanese surrender in order to end the war. One was to invade Japan and another was bombing it. The US previously did try to invade Japan, but suffered major casualties, if they were to invade more, the US would lose a lot of soldiers and material. Dropping the atom bomb was the better option as it didn't risk any US lives and it was it scare the Japanese into surrendering.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
