It is useful as evidence for the USAs involvement in the formation of NATO because America knew the Capitalist countries would be stronger and more able to stand up the Soviet uNion if they were in a pact However Source B is not useful because it is printed in a US newspaper and shows the Soviet Union to be aggressive. The newspaper wants to show the Soviet Union in a bad light and win over its American readers. The content of Source C is useful in letting us know why the USA formed NATO as it clearly states “There are aspects of Soviet policy which have caused a feeling of insecurity in Europe

It Goes on and say “there is the Soviet acceptance that there will be a series of conflicts with the West.” This was proven to be the case in the Berlin Airlift. So NATO was set up to “reduce or end this insecurity by making strong and clear statements”. However this source is unreliable because It is from an ambassador to President Truman, again it is an American Perspective, so they are peddling the line that it was a defensive measure when the Soviet Union may see it as aggressive.

The Soviet Union and East Germany built the Wall in 1961 to stop refugees fleeing to the West. It was important because it heightened the dispute between the USA and the Soviet Union about the presence of Britain, France and the USA in West Berlin. However, it was also important because it avoided a war between the USA and the Soviet Union and it made Khrushchev seem a strong leader. In addition, the Wall was important because it made the USA determined to support West Berlin as was seen by Kennedy’s visit in 1963. It also meant Khrushchev backed down from his ultimatum

In 1956, the Hungarian people rose up against the Soviet forces and demanded freedom. It was important because it showed that the Soviet Union could be challenged but it was also important because it showed that the Soviet Union was not concerned about international reaction.
