The British posture was totally different. They had lost a lot of their strength in First World War and they stood up against Hitler alone for more than one year. They were simply broke. Therefore, their intention was to try to retain as much of the old colonies as they could. For the British winning the war was vital. However, a Britain without colonies would be too weak. Historically, all these European wars were over the exploits of the colonies. However WWII was different, as it would incorporate other factors that did not exist before, namely socialism, third world people's awakening, and a US that might not go back into its shell. Churchill did not want to permit America and Russia to become the sole superpowers. However, at the end of the day, the American and Russian manpower, natural resources, and military victories caused The British, French, Spain, Germany and Japan to become irrelevant powers.

The Russian posture
The Russian posture was absolute brutality. Stalin wanted to beat Hitler and gain as much territory as possible. Stalin was able to achieve his goal, Hitler was defeated and Eastern Europe was devoured. Stalin's approach to the war was totally different to rest of the allies. He was willing to sacrifice millions of people to gain more territory. 27 million Russians were killed in the Second World War while Germans who fought in several more fronts had 6,000,000 casualties. The total number of American casualties was less than half a million. On average, Russians lost 10,000 men a day until the war was over. Since WWII was the fourth major invasion of Russia from the west, they were justifiably paranoid of future Hitlers. Stalin was turning Russia and all its captured areas in Eastern Europe into a fortress. Stalin managed to put 500 divisions into the conquered territories of Eastern Europe. He used the capitalists to beat Hitler but he was not a friend of the capitalists. His paranoia and mischief made the environment quite uncomfortable for an alliance.

Unfortunately, Americans didn't have much foreign experience. They had been traditionally isolationists and their only significant foreign adventure was their participation of one year at the end of the First World War. They didn't have the political structure or the proper intelligence organization to do anything significant. They simply followed the British rule. That was because they trusted the British, unfortunately, and they both spoke the same language. By doing this they inherited the ugly reputation of the British who had plundered the most of the planet Earth for 200 years. I can claim, without any doubt, at that time the British were the most hated people on earth. They were more hated than Hitler and Stalin. However, these facts were not universally known because the rulers of the most of the countries which were close to the British empire were actually British puppets and wouldn't permit their people to have any say in the foreign policies of their countries.

The Main Players of the Cold War
Although the cold war included significant military confrontations such as: Korea, Vietnam and Cuba, most of the battles were fought through intelligence organizations, which are as famous as any other cabinet offices.
The Central Intelligence Agency
The United States didn't have an intelligence agency. The American Army had a special branch called the OSS, which mostly consisted of commandos who were in charge of fighting Mr. Hitler. Once the war was over, President Truman took the people from the OSS and laid the foundation for the CIA. The newly formed organization was quite immature and inexperienced in dealing with complex events of the post war period. Since Americans were superior to the other countries in technology, their method of dealing with intelligence issues was based mostly on technology rather than on the human element. In other words, there was heavy emphasis on technology and poor attendance to spies.
