Conclusion to our question

The Cold War was fought over a long period of time and according to our groups research on who was to be blamed:

1. Origins:
No one was to take all the blame for it was started by misunderstandings.

2. Developement:
USSR was more to be blamed due to the pointless "catching up" they were always doing, causing tension.

3. Crisis:
USSR is more to be blamed on the Berlin Blockade and Cuban Missile Crisis, however they did recover in the Cuban Missile Crisis to reach an agreement with the USA with Krushchev giving in to USA. USA was to be blamed for the Archer 83 incident, therefore both were about equal with the blame, afterall it was a crisis.

4. End of Cold War:
The end of Cold War was brought about mainly by the change in USSR leadership. However it would have also ended with USSR breaking out from total Communism and into component countries. Therefore,since there was no country trying to aggrevate the situation,we would not blame any nation for resolving this Cold War, instead we should thank Mikhail Garbochev for seeing the light that the USSR were suffering and taking up some Capitalist's policies.

Overall:
USSR was to be blamed to a larger extent even though USA would take some blame too.
