From 1951-1953, British forces were fighting alongside the Americans in the Korean war. The relationship between the two countries were close, but Britain was clearly subordinate to the US in the decision making. The 1960s & 1970s saw increasing decolonisation of Britain's empire Which meant that the importance and value of the British to the Americans diminished. During the Suez Crisis (1956), Britain could not act independently of, and certainly not in opposition to, the US.
