A key question today is whether India and the United States can or should develop ever-closer ties as a way of countering China's desire to be the dominant power in the broader Asian region. In Fateful Triangle, Tanvi Madan argues that history shows that such a partnership is neither inevitable nor impossible. Drawing on documents from India and the US, Fateful Triangle contends that China's influence on the US-India relationship is not a recent phenomenon. It demonstrates that US and Indian perceptions of and their policies towards China shaped US-India relations in three crucial decades, from 1949 to 1979, in significant and complex ways. Fateful Triangle updates our understanding of the diplomatic history of US-India relations, highlighting China's central role in it, reassesses the origins and practice of Indian foreign policy and non-alignment, and provides historical context to the interactions between the three countries.
