More general forms of the scapegoat hypothesis have been endorsed by numerous modern international theorists. Wright (1965, 727) argues that one of the most important causes of war is the perception that war is a "necessary or convenient means . . . to establish, maintain, or expand the power of a government, party, or class within a state." Haas and Whiting (1956, 62) argue that statesmen "may be driven to a policy of foreign conflict-if not open war-in order to defend themselves against the onslaught of domestic enemies," particularly against enemies arising from the inequities generated by rapid industrialization and social change. Rosecrance (1963,306) argues that the domestic insecurity of elites is one of the most important causes of war and that "domestic stability and internal peace [is] the vehicle of international stability and external peace."
