There is a law that governs everything built for war, and it has never been repealed:
In war, every product and every person gets found out.
Not in the demo. Not in the pitch. In contact — against an enemy who adapts, jams, deceives, and shoots back. The question for every founder and every investor in defense is not whether you will be found out. It is when, where, and at what cost.
A sword that has never touched the stone is not a sword. It is a sword-shaped object. And most of what the West calls its arsenal today — and most of what its brightest new companies are building — is exactly that: unsharpened, untested, and marketed as ready.
The whetstone
There is one place on earth where the stone exists.
Ukraine is fighting the largest, most technologically advanced war since 1945 — against the exact adversary, and the exact axis, the free world will face everywhere else. The entire discipline of modern war — how drones hunt, how jamming kills, how humans and machines actually fight together — is being written there, nightly, by the people living it.
You cannot learn this from a briefing. I say that as a man who has spent twenty years on both sides of the briefing table. The distance between what Washington believes and what a soldier at the front knows is the most dangerous gap in the free world — and no report crosses it. Only presence does.
I learned that lesson long before this war. In Iraq, the thing that saved my troop from a truck bomb was not technology. It was the local police we fought beside and lived among — embeddedness, presence, trust. War is a human endeavor, and humans do not extend trust across an ocean.
That is what "sharpening the sword" means. It is not testing a product. It is testing a company — its engineers, its assumptions, its honesty — against the only judge that cannot be lobbied.
The ones who go during
In 2022, when Kyiv held, my wife and I faced the decision of our lives: stay in the safety of America, or go home to the war. I told her something I believe more with every passing year:
The people who lead a country after a war are the ones who were there during it. Everyone else is a carpetbagger.
The same is true for companies. When this war ends — and it will not end the way most people think — there will be two kinds of defense companies: the ones whose products and people were sharpened here, trusted here, remembered here — and the ones who watched. The contracts, the alliances, and the history will belong to the first kind.
The objections — and the rules
Every founder who decides to go hears the same five sentences before they leave: there's no money in Ukraine · it's corrupt · it's not the war we'll fight · nobody requires it · your investors won't allow it.
I've spent three years watching those five sentences stop brilliant people at the border. Every one of them is either half-true or exactly backwards — and in the talk, I take them apart one by one, with receipts.
And for the ones who come: there are ten rules of conduct that decide who becomes real here and who goes home. Like Fight Club — except the first rule of Ukraine, you say out loud, and I'll give it to you now: Be for Ukraine. The country can tell in one meeting who came to give and who came to take.
The other nine, I teach with the stories of the companies that lived them — including the failures. That, plus the map of what comes after this war, is the rest of the talk.
One part of this manifesto remains. It's not about war, the world order, or Ukraine.
It's about whether you're the kind of person any of this was written for.
