The confrontation with Indonesia cut to the heart of Britain's desire to retain global power status in the 1960s and was central to decolonisation and British defence policy across South-East Asia. Factors such as the need to maintain a military base in Singapore drove strategy and this confrontation became a major commitment - close at times to escalating into full-scale regional war. However, 'the Confrontation' was not recorded as a conflict of this scale, and Britain was cast into a passive and defensive role. Here, David Easter reveals a radically different view, persuasively making the case that Britain waged a secret and aggressive war against President Sukarno's Indonesia. It was the covert nature of operations and the deliberate decision of British policy-makers to keep the full extent of this conflict away from public scrutiny that has allowed it to be overshadowed in the annals of history.
