Washington’s role in the world is diminishing. What comes next?
Has American dominance across global foreign policy, finance, and military affairs been a source of stability or conflict? Some believe Washington’s status as the last great power has been a force for good. Others disagree.
Maintaining its hegemony has demanded that Washington divide the world into marginalised adversaries and dependent allies. NATO’s supremacy in Europe was seen by many of the West’s leading lights as having created a lasting peace on the continent. At the same time though, it has also been the main source of conflict as the bloc expanded towards Russian borders.
We are now living in an age when that American dominance is coming to an end, and its security guarantees are losing their credibility. If a unipolar world order reduced the prospect of conflict, will previously dormant forces be unleashed as vulnerable states are overwhelmed by their aggressors? Alternatively, though, will stalemates and ceasefires be longer lasting as nations previously emboldened by US backing are forced to find lasting solutions with their adversaries, rather than languishing behind Washington’s protection?
When American promises don’t matter any more
The US was, understandably, hesitant to admit defeat and leave Afghanistan as it would cause a “credibility crisis.” Its allies would no longer be able to base their foreign policy on the assumption of its protection and collective hegemony, and they would have to pursue an independent foreign policy and compromise with their adversaries. American power would decline, due to a diminishing ability to exert influence over its dependent allies, and to marginalise its adversaries.

If Ukraine and Taiwan did not have full faith that the US would offer them protection, then their positions as Washington’s frontlines against Russia and China would not be tenable and they would have to seek peace with their adversaries. Without steadfast US support, Ukraine would have to abide by the Minsk Peace Agreement, and Taiwan would need to halt its push for secession from China.
The failed US pursuit of regime change in Syria has resulted in both the Arabs and Turkey moving gradually towards reconciliation and a workable peace with Damascus. American efforts to reach an agreement with Iran, and the failure to decide the outcome of the conflict in Yemen, has similarly incentivised Saudi Arabia to re-establish diplomatic ties with Tehran, and paved the way for negotiations on improving bilateral relations and ending the war in Yemen.
