Abstract in English:
The Trump administration should not take up its work under the assumption that the United States, with only 5 percent of the world’s population and around a quarter of the world’s economy, can continue to be an indispensable presence on the world stage. America’s relative decline since 1945 seems to be a byproduct of the post-World War II system it created along with its allies and partners, in which the United States worked to bring millions out of poverty, give other nations incentives to strengthen their governance structures and institutions, and establish global norms of behavior. That effort sought to ensure no worldwide conflicts recurred. However, fostering an environment where states, groups, and individuals could be further empowered naturally eroded America’s once-monopolistic strength; the United States has brought humanity to a new era where many are powerful and many can potentially lead.
