Now that you understand the basics about the Berlin Airlift, formulate three questions about this event that you want to know mo
tangare [24]

The correct answer to this open question is the following.

The three questions about the Berlin Airlift are the following.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

2.- What was the reaction of the western European allies to that decision?

3.- How everything ended after almost one year of the blockade?

Here are my answers.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

The Soviet Union needed to have a powerful answer against the allied forces after the recent events. Furthermore, Joseph Stalin wanted to show his power. After Joseph Stalin ordered the blockade of Berlin, people were totally disconnected and could not have any type of contact with the outer world.

2.- What was the reaction of the western European allies to that decision?

The United States and Great Britain would not allow the Soviet Union to spread its influence by cutting Americans off from friendly peoples and territories. That was mainly the goal when they decided to start the Berlin airlift.

That is why on June 26, 1948, Great Britain and the United States started to send help and supplies to Berlin using airplanes. President Harry S. Truman wanted to avoid a direct confrontation with Russia or the possibility of another war in the region, that is why he opted for help by air.

3.- How everything ended after almost one year of the blockade?

In May 1949, the USSR lifted the blockade. It was clear to Stalin that his blockade has failed.
