AE-HN520 - America since 1945 A Global Power

This course will focus on America’s role on the world stage from the end of the Second World War to the present. The course will begin by assessing America’s position in relation to other nations as the Second World War concludes. We will consider America’s economic, political, military, geopolitical, and cultural power and how all of these have contributed to America being a dominant force globally since 1945. We will discuss the importance of the American economy as the world’s largest economy in the twentieth century and the rise of the Chinese economy to overtake America in the twenty first century. We will examine American military power and spending since 1945 and consider how this power has been used including in conflicts such as the Korean and Vietnam Wars. This course will also examine America’s motivation for becoming involved in various global issues and events over the course of the twentieth century. We will ask whether America becomes involved in such issues and events to protect American freedom and interests around the globe or has it, as it has claimed, a greater goal of ensuring the freedom and stability of other nations also. America’s political influence especially in Europe, Asia, and Latin America and how it was used to ensure American interests were protected will also be discussed. Finally, we will look at the global reach of America cultural influences and try to analyse what role they play in facilitating America’s position as a global power.

The course does not presuppose an in-depth knowledge of American history or politics.
