US Hegemony is in Decline...So What?

 

This morning I woke up to a particularly strange news article.

The Spanish government slammed the door on U.S. requests to use their airbases. They didn’t just say 'not now'; they effectively evicted U.S. operations from their soil and skies.

The Spanish Defense Minister Margarita Robles went a step further, describing the US/Israel <> Iran conflict as "profoundly illegal and profoundly unjust.”

The reaction of Spain was perhaps the most vocal, but they are not alone.

• France recently blocked aircraft carrying military supplies to Israel from using its airspace.
• Italy denied permission for U.S. military aircraft (specifically bombers) to land at the Sigonella air base in Sicily.
• While Turkey continues to host U.S. forces at İncirlik Air Base, the Turkish Foreign Ministry recently dismissed claims that they would allow the stationing of aerial refueling aircraft for the Iran war, calling such reports "unserious."

For decades, the alliance was built on a series of 'Yes's. 

   Yes to bases. 

   Yes to airspace. 

   Yes to the American umbrella. 

But after a year of trade threats and Greenland-sized insults, Europe has found a different word.

Spain said No to Rota. 

Italy said No to Sigonella. 

France said No to the munitions flights. 

The 'unipolar moment' is being dismantled, one 'No' at a time.

This isn’t just a logistical headache for the Pentagon; it’s a nervous breakdown for the post-WWII order. We’ve seen friction before, but 1986 and 2003 feel like playground spats compared to this.

Is this just another temporary rift in a long marriage? Or are we watching the messy, public divorce of the West? 

• In 1986, it was about a single mission (Libya). 
• In 2003, it was about a single war (Invasion of Iraq). 
• In 2026, it feels like something else.

Not a disagreement over tactics—but a quiet rejection of the premise itself.

Maybe this is just another rift.

Or maybe this is how it starts.

Not with collapse.

Not with declarations.

But with a few countries, one by one, deciding that “No” is an option.

---

To understand why the 'No' is so deafening, we have to look at what the 'Yes' actually bought us.

If the world is starting to say “No,” then it’s worth asking a more basic question:

what exactly was the “Yes” built on?

We can break it down into five things.

1. Security Guarantee (Hard Power)

What it is:

• Military protection
• Nuclear umbrella
• Global force projection

Mechanisms:

• NATO
• Bilateral treaties (Japan, South Korea)
• Forward bases (Germany, Italy, Turkey, etc.)

What countries got:

• External defense without full military cost
• Reduced need for independent nuclear programs
• Stability against regional threats

Why it mattered:

This is the foundation. Without this, nothing else holds.

2. Economic System (Global Trade Architecture)

What it is:

• A rules-based global trade system
• Access to the largest consumer market in the world

Mechanisms:

• World Trade Organization
• International Monetary Fund
• World Bank

What countries got:

• Export-led growth (Germany, Japan, China, Korea)
• Predictable trade rules
• Capital access and development funding

Why it mattered:

The U.S. didn’t just dominate—it enabled growth for others.

3. Monetary Backbone (Dollar System)

What it is:

• The global reserve currency system centered on the U.S. dollar
• Financial Plumbing: The secure messaging (SWIFT) and clearing networks (CHIPS) that provide the digital architecture for moving dollars globally.

Mechanisms:

• United States Dollar
• Petrodollar system
• Deep U.S. Treasury markets

What countries got:

• Stable reserve asset
• Liquidity in crises
• Global trade settlement standard

Why it mattered:

This is the invisible infrastructure of globalization.

4. Technological & Innovation Engine

What it is:

• The U.S. as the primary source of frontier innovation

Mechanisms:

• Silicon Valley ecosystem
• Research universities
• Venture capital networks

What countries got:

• Access to cutting-edge tech
• Spillover innovation
• Platforms (internet, software, chips, GPS)

Why it mattered:

The U.S. didn’t just provide security—it provided the future.

5. Normative Order (Soft Power / Legitimacy Layer)

What it is:

• A shared ideological framework

Mechanisms:

• Democracy, rule of law narratives
• Cultural exports (media, education)
• Institutions and diplomacy

What countries got:

• A “justification layer” for alignment
• Legitimacy in domestic politics
• A sense of shared identity (“the West”)

Why it mattered:

Power alone doesn’t sustain hegemony—belief does.

So back to the original question.

Does this "No" represent a temporary glitch in a US-led unipolar world, or are we seeing the beginning of a multipolar world?

No one has the answer.

But I can point to some structural changes to the hegemonic system that should be examined.

1. The Threat Environment Has Fragmented (Post-Cold War Reality)

• Collapse of Soviet Union removed a single, existential enemy
• No longer a binary world (US vs USSR)

Effect:

Security umbrella became less existential, more optional

Alignment is no longer automatic—it’s situational

Before: “We need the U.S. to survive”

Now: “Do we need the U.S. for this specific issue?”

2. Allies Have Become Capable (Military Maturation)

• South Korea → advanced military + domestic arms production
• Poland → rapidly expanding defense spending
• Europe broadly → latent industrial + technological capacity

Effect:

Reduced dependency on U.S. hard power

More willingness to act independently

Dependence → Optionality

3. Economic Power is Distributed (Rise of Others)

• China as a peer competitor
• India as a major growth engine
• EU as a regulatory/economic bloc

Effect:

U.S. is no longer the only path to growth

Countries can hedge between systems

4. Information & Technology Diffusion

• Innovation is no longer U.S.-exclusive
• Industrial policy + state-led tech ecosystems rising globally

Effect:

U.S. tech advantage is still real—but no longer uncontested

Partners are also competitors

5. Normative Fragmentation (Loss of Shared Story)

• “The West” as a unified identity is weaker
• Domestic politics diverging across allies

Effect:

Alignment no longer justified by shared ideology alone

Legitimacy must be re-earned, not assumed

---

If these shifts—the fall of the USSR, the rise of the Chinese engine—have been grinding along for thirty years, why is the engine suddenly seizing up in 2026?

Because power isn’t just about capacity; it’s about predictability.

That predictability is being shaken at its foundation. The world’s guarantor, the United States, has pivoted from the architect of global order to its primary disruptor under the highly unpredictable second term of Donald Trump.

The "invisible infrastructure" is no longer a given; it is now a leverage point. Here are the forces accelerating the collapse right now:

1. Perceived Unreliability of U.S. Policy

• Rapid swings in foreign policy direction
• Trade threats toward allies
• Transactional framing of alliances
• “If they don’t pay, we won’t defend them.” “NATO is obsolete.”

Effect:

Allies start planning for “what if the U.S. isn’t there?”

Hedging behavior increases

Power isn’t just strength—it’s integrity

2. Weaponization of Interdependence

• Sanctions regimes
• Financial system leverage (USD, SWIFT access)
• Export controls (chips, etc.)
• "They can go find another sucker Nation. There is no chance that BRICS will replace the U.S. Dollar... and any Country that tries should say hello to Tariffs, and goodbye to America!"

Effect:

Countries realize dependence = vulnerability

Incentive to build alternatives (FX, supply chains)

3. Cost Asymmetry of U.S. Actions

Wars or conflicts where:

• U.S. bears less direct cost
• Allies bear geographic/economic consequences
• "All of those countries that can't get jet fuel because of the Strait of Hormuz, like the United Kingdom, which refused to get involved in the decapitation of Iran, I have a suggestion for you: Number 1, buy from the U.S., we have plenty, and Number 2, build up some delayed courage, go to the Strait, and just TAKE IT. You’ll have to start learning how to fight for yourself... Go get your own oil!"

Effect:

Allies ask:

“Why are we taking on risk for decisions we didn’t make?”

4. Domestic Political Pressure Within Allies

Voters less willing to:

• Support foreign wars
• Accept economic fallout
• Defer to U.S. leadership automatically
• "I hear that they like Obama better... because he didn't ask for anything. We were like the stupid country of the world and we're not going to be the stupid country of the world any longer."

Effect:

Leaders have less room to say “Yes”

“No” becomes politically viable

5. Credible Alternatives Emerging (Even if imperfect)

• China as economic partner
• Regional blocs gaining weight
• Non-alignment becoming viable again
• "The idea that the BRICS Countries are trying to move away from the Dollar... is OVER."

Effect:

The cost of saying “No” to the U.S. decreases

---

You don’t need a better system

Just a good enough alternative.

Ironically, no adversary needed to break the system from the outside.

It’s being loosened from within—by unpredictability, by pressure, by a shift from partnership to transaction.

The world isn’t rejecting American power.

It’s starting to question the terms.

---

Where does that leave us?

Option 1. We are still in a unipolar society based on US hegemony and what we are observing today is a temporary recalibration.

Option 2. We are seeing US hegemony beginning to weaken and are experiencing a fractured unipolar world.

Option 3. US hegemony is over and what we are experiencing is the beginning of a multipolar world.

Honestly? I think we are in Option 2.

The US is still the apex predator, but is either unwilling or unable to act as the hegemon.

A true hegemon provides "public goods" to keep everyone "bought in",

not a "stick" to keep others in line.

A true hegemon abides by the "rules" it has helped create,

not be the one that constantly "breaks" it.

A true hegemon need not be "benevolent",

but it absolutely needs to be "predictable."

What I expect to see more of:

1. More leaders will visit South Korea, Taiwan, and China.

>>>

When what you "sell" is neither stable nor predictable,

your buyers will diversify their supply sources.

2. More countries will increase their military spending. Germany and Japan might change their constitution.

>>>

If you can't be trusted to "show up" with your stick when needed,

your buyers will carry sticks of their own.

3. Automatic Yes's will be replaced by conditional Yes's, and sometimes with outright No's.

>>>

If the only answer to every problems is to "wave a stick" around,

expect others to call you out on it.

4. The fragmentation of the "Plumbing" (SWIFT, USD, Tech)

>>>

If the global "operating system" is treated as a weapon of compliance rather than a neutral utility,

the world will stop trying to join your network and start building their own.

5. The death of "Universal Norms" in favor of "Strategic Interests"

>>>

When the "Justification Layer" of democracy and rule of law is stripped away to reveal raw transaction,

loyalty dies—and in its place, everyone becomes a free agent.

The irony of 2026 is that the system wasn't toppled by a rival superpower.

It didn't fall to a Chinese "Yes" or a Russian "No."

It is being dismantled by the very architect who realized that maintaining an empire is expensive, and decided that being a landlord was more profitable than being a leader.

But as Spain, Italy, and France are showing us this morning:

When the landlord stops fixing the roof and starts threatening the tenants, eventually, the tenants find a new place to live.
