• Sommario/riassunto: Between 1968 and 1980, fears about family deterioration and national decline were ubiquitous in American political culture. In No Direction Home, Natasha Zaretsky shows that these perceptions of decline profoundly shaped one another. Throughout the 1970's, anxieties about the future of the nuclear family collided with anxieties about the direction of the United States in the wake of military defeat in Vietnam and in the midst of economic recession, Zaretsky explains. By exploring such themes as the controversy surrounding prisoners of war in Southeast Asia, the OPEC oil embargo
