A second defining development during the half century after World War Two was a multifaceted struggle to make democracy more meaningful. the United states fought World War Two, as it has fought most of its wars, in the name of democracy. But democracy had a very different meaning at that time than it would when the century ended. In the middle of the twentieth century, millions of Americans were denied basic citizenship rights. Formal political power was much less evenly distributed than it later would be, individual rights far less robust, and openly discriminatory rules and practices widespread. who could vote, how legislatures were constituted, who could use which public facilities, who was allowed to work in which kind of job, and how the criminal justice system operated all were very different in the mid 1940s than they would be a generation later. In businesses, families, schools and churches, on playing fields and in communities, the hierarchies of power and opportunity were structured by race, sex, religion, and ethnicity. Authority was wielded by fewer hands, with fewer challenges and less consultation, than we now take for granted. Furthermore, the postwar struggle by African Americans for freedom, rights, and equality catalyzed a democratic revolution that transformed the United States and echoed around the world. Expanded notions of rights and democracy and new modes of political action spread from the struggle for racial justice to ever more arenas of American life, changing ideas and practices in local communities, national institutions, and intimate private relations.But even as this democratic revolution reached its peak, power began moving out of the public realm and into private ones, especially the corporate world.
after analysis of American Empire, after World War Two, American way of foreign policy and way of empiricism have been changed a lot. On later, it has impacted on rest of the world.
