This chapter describes the efforts of various Republican presidents and congressional leaders to strike balances between nationalist and internationalist priorities between the 1960s and 2015. Barry Goldwater championed a hawkish Sunbelt conservatism that in the long run helped remake the Republican Party. President Nixon pursued a foreign policy based upon assumptions of great-power politics and realpolitik. President Reagan led an ideologically charged effort at anti-Communist rollback, although he was careful not to overextend the United States in any large-scale wars on the ground. Republicans during the Clinton presidency struggled to reformulate conservative foreign policy assumptions in the wake of the Soviet Union’s collapse. George W. Bush remade conservative foreign policy into a war on terror, aiming at the democratization of the Greater Middle East. Finally, during the presidency of Barack Obama, Republican foreign policy factions once again splintered, paving the way for a conservative nationalist resurgence.
