The U.S. and Iran just traded fire in the Strait of Hormuz.
Missiles launched. Drones swarmed. Destroyers engaged in “self-defense strikes.”
Both sides claim the other shot first, and the fragile ceasefire is hanging by a thread.
But this isn’t just another Middle East skirmish.
It is the exact repetition of a 400-year-old geopolitical earthquake that ended a global superpower’s dominance over the world’s oceans.
To understand what happens next to American naval supremacy, we have to look back to the year 1622.
The Empire That Owned the Ocean
In the early 1600s, Portugal was the undisputed master of the seas.
They didn’t just trade on the Indian Ocean — they claimed they owned it.
Through a brutal system of naval dominance, the Portuguese forced every ship to buy a permit called a cartaz. If you didn’t pay their exorbitant fees, your ship was sunk.
They were a small nation of barely a million people, but their massive galleons and ruthless tactics allowed them to push around empires ten times their size.
Sound familiar?
To control the flow of global wealth, Portugal seized the ultimate chokepoint: the island of Hormuz.
Sitting right at the mouth of the Persian Gulf, Hormuz was the gateway for the world’s most valuable commodities — spices, silk, pearls, and the lifeblood of global trade.
For over a century, the Portuguese sat in their impregnable fortress on Hormuz, taxing the world and projecting power deep into the Middle East.
They believed their technological superiority made them invincible.
They were wrong.
The Asymmetric Awakening
By 1622, the local power — the Safavid Empire of Persia (modern-day Iran) — had had enough.
Shah Abbas the Great knew he couldn’t beat the massive Portuguese galleons in a head-to-head naval battle.
So he changed the rules of the game.
First, the Persians targeted the Portuguese supply lines. They captured the nearby island of Qeshm, cutting off the fresh water supply to the fortress at Hormuz.
Then, they deployed asymmetric warfare: instead of building massive ships, the Persians dug trenches. They used long-range snipers to pick off Portuguese officers from behind earthworks where European cannons couldn’t reach.
“Iranian snipers were able to pick off Portuguese soldiers inside their fort. The Iranians hid in trenches and behind earthworks, so the Portuguese snipers could not effectively return fire.” — Cameron Winter, The Fall of Hormuz, International Journal of Military History (2025)
But Shah Abbas’s masterstroke was economic.
He formed an alliance with an emerging rival power: the British East India Company. The Persians offered the British a cut of the lucrative silk trade if they provided the naval transport the Persians lacked.
Faced with a determined local force using asymmetric tactics, cut off from supplies, and outmaneuvered diplomatically, the Portuguese commander surrendered in just twelve days.
The invincible empire was expelled from the Gulf forever.
The Pattern Recognition
History doesn’t just rhyme — it operates on a brutal, mathematical calculus.
When a distant superpower tries to control a vital maritime chokepoint through sheer force and economic coercion, it eventually triggers a coalition of local resistance.
The Portuguese relied on massive, expensive galleons. The Persians used trenches, snipers, and sappers.
Today, the U.S. relies on multi-billion-dollar destroyers. Iran uses swarms of cheap drones, fast boats, and shore-based missiles.
The technology changes, but the geometry of the strait remains exactly the same.
A narrow waterway neutralizes the advantage of massive ships. It turns a blue-water navy into sitting ducks for asymmetric, land-based attacks.
When the Portuguese lost Hormuz, it wasn’t just a military defeat. It signaled to the world that their global protection racket was vulnerable.
It was the beginning of the end for their empire.
The Ancient Warning
The clashes we are seeing today in the Strait of Hormuz are not isolated incidents.
They are the stress tests of an empire.
If the U.S. is forced to retreat from the Gulf — or if the cost of maintaining control becomes economically ruinous — the ripple effects will shatter the global financial system.
The U.S. dollar’s status as the world reserve currency is tied directly to the military’s ability to guarantee the safe passage of global energy.
If that guarantee fails, the price of everything changes.
You cannot control the world if you cannot control the chokepoints.
5 Things You Can Do This Week
When global supply chains are threatened at major chokepoints, the impacts hit your local grocery store and gas station within weeks. Here is how to prepare:
1. Audit Your Energy Dependence. If the Strait of Hormuz closes, fuel prices will skyrocket overnight. Keep your vehicles topped off and consider investing in a dual-fuel generator or solar backup for critical home systems.
2. Stockpile Essential Medications. The global pharmaceutical supply chain is incredibly fragile. Work with your doctor to secure a 90-day backup supply of any life-saving prescriptions. For alternative health strategies and natural resilience protocols, check out the resources at Freedom Health Daily.
3. Accelerate Your Food Independence. Don’t wait for shipping lanes to freeze. Start building a deep pantry of calorie-dense, long shelf-life foods. If you want to take it a step further and grow your own food in any space, the 4 Foot Farm Blueprint is the perfect place to start — even with limited space.
4. Secure Physical Assets. When geopolitical instability spikes, digital wealth can evaporate. Ensure you have physical cash on hand and consider diversifying into tangible assets that hold value outside the banking system.
5. Harden Your Home Base. Economic shocks lead to local instability. Review your home security protocols, upgrade your perimeter defenses, and ensure your family has a clear emergency communication plan. For advanced preparedness strategies, visit Survival Stronghold.
