How the US shaped the world: 250 years of power and policies

In the 250 years since, US governments have claimed that preserving the ideals of democracy, human rights and fundamental freedoms are the main motivators of the country's foreign policy.  Americans, however, have growing doubts about whether the United States has lived up to its founding values.

In 2024, 72% of Americans surveyed agreed with the statement that democracy in the United States "used to be a good example, but has not been in recent years." DW examined how the country's foreign policy objectives and tactics have changed over 250 years — showing how US governments have increasingly pursued goals through military force rather than diplomacy. Political scientists Monica Duffy Toft and Sidita Kushi have identified more than 500 US military interventions in the past 250 years. "While in the past the US assumed rationality for many of its rivals, in the post-9/11 era, that belief in the rationality of their enemies seemed to have dissipated," said Kushi, an assistant professor at Mount Holyoke College, a private liberal arts university in Massachusetts.

"The idea was then: 'If we cannot reason with our enemies, if we cannot use diplomacy with our enemies, all we have is violence — all we have is the use of force,'" Kushi said. "And, with a dramatically growing Department of Defense budget and a withering Department of State budget in the post-9/11 world, what happened is: If all you have is a hammer, everything looks like a nail." Though Latin America has most consistently been the site of US interventions since the early 19th century, countries in Asia, including the Middle East, have been an increasing focus of military intervention in recent decades. "There is a clear shift in our data in the US moving towards the Middle East, North Africa and sub-Saharan Africa for many of its interventions," Kushi said.

"Arguably, much of that can be explained by the post-9/11 global war on terror. It can also be explained by the US's power projection capabilities as the unipolar power. After the end of the Cold War, with a growing military capacity, the US could afford to project more of its power all over the world and, of course, redefine its interests so that the world at large becomes related to US interests."  It's not only that the regional interested shifted, the objectives, too, changed with time.
