In International Relations Since 1945: East, West, North, South, Lundestad traverses a vast historical timeline of International Relations (IR) that encompasses the Cold War (1945-1993) and the post-Cold War period up to 2017. In the book, Lundestad demonstrates that trends in the U.S. and Russian foreign policy have remained constant, although the pursuit of goals is affected by changes in political personalities, ideological differences, and political and economic systems.
