For roughly half a century after World War II, global politics possessed a peculiar clarity. The United States anchored one system, the Soviet Union another. Countries maneuvered between them, and regional conflicts complicated the map, but the two great poles remained unmistakable. After the Soviet Union disappeared, American power became even more central. For better or worse, Washington became the principal organizer of the international system.
That world is passing.
The Trump foreign policy has accelerated the change. Its argument is countries living under the American security umbrella should assume greater responsibility for their own defense. We have seen this in Ukraine, where European states have taken on a larger share of the burden. More broadly, American foreign policy increasingly seems to emanate directly from Donald Trump, Pete Hegseth, and Marco Rubio, supplemented at times by American business figures acting as informal diplomats. It is a different style of leadership, less institutional and personal and transactional.
But there is a consequence to telling other countries to take greater responsibility for themselves.
Eventually, they do.
And countries that learn to defend themselves also learn to make decisions for themselves.
The world was already moving in this direction. China is an economic and military power with its own interests. India is an emerging giant with little inclination to subordinate its foreign policy to anyone. The Middle East has become far too intricate for a simple American-led framework. Sunni and Shia interests, Israeli security ambitions, Turkish aspirations, Gulf wealth, Iranian influence, and the Palestinian question produce alliances that overlap rather than align neatly.
The latest development is particularly revealing. Turkey, a NATO member with one of the world’s largest militaries, has joined Saudi Arabia and nuclear-armed Pakistan in a new defense arrangement. Egypt has participated closely with those countries in regional diplomacy but, at least for now, has remained outside the pact.
That distinction may be as important as the alliance itself.
We are not watching another NATO or Warsaw Pact emerge. We are watching countries construct overlapping relationships according to their own interests. Turkey can remain in NATO while cooperating strategically with Saudi Arabia and Pakistan. Saudi Arabia can maintain close relations with Washington while developing security arrangements that do not depend upon it. Pakistan can participate while remaining attentive to China and its rivalry with India. Egypt can cooperate with all three and still decline formal membership.
This is what a genuinely multipolar world looks like. Not several neat camps, but a web.
The United States, meanwhile, is experiencing an unusual degree of strategic dispersion. The conflict with Iran consumes military resources, diplomatic attention, and weapons stockpiles. Russia remains consumed by Ukraine. Both Washington and Moscow find their freedom of action constrained, while regional powers have greater incentive to organize without waiting for either.
There is an irony here.
For decades, American presidents complained that allies were not carrying enough of the burden. Trump has made the complaint a central principle of foreign policy. Europe should spend more. Asian allies should defend themselves. Other countries should stop assuming that American money and American soldiers will always be available.
But burden sharing and influence sharing are two sides of the same transaction.
The American-led order may have seemed expensive. It required military bases, foreign aid, diplomatic attention, international institutions, and occasionally the willingness to defend countries whose immediate importance to ordinary Americans was difficult to explain. But those expenditures purchased more than security.
They purchased influence.
Countries consulted Washington because Washington mattered to their security. Alliances brought obligations, but they also brought leverage. Foreign assistance produced relationships, access, goodwill, and the ability to shape decisions before they were made. Soft power was part of the bargain.
As the United States asks others to assume greater responsibility, those countries will inevitably develop greater strategic independence. They may make choices Washington applauds. They may make choices Washington dislikes. Increasingly, they may make choices without asking Washington at all.
That does not necessarily mean American decline. But it will be a different world.
No nation, however powerful, can indefinitely organize every region or dictate every alignment. The challenge is preserving influence where it matters most while accepting that other nations have interests of their own. That becomes harder when withdrawal is confused with leverage. Influence surrendered is not always influence that can later be summoned when needed.
The emerging alliances in Europe, Asia, and the Middle East may therefore represent something larger than diplomatic rearrangement. They are evidence that countries live in a world in which American leadership is less predictable and American protection less automatic.
For decades, Washington asked its allies to carry more of the burden.
They increasingly are.
The question is whether Americans understood the other half of the bargain.
Countries that learn to defend themselves also learn to decide for themselves.
The world America asked to become more independent may be doing exactly that.
