The deal is done. But who owns it? The Iran nuclear agreement, resurrected in Geneva, has a new public face: JD Vance. The vice president stood at the podium, not the president. That is the tell.
Vance's presence was strategic. Trump remains the shadow. He gets the credit if it holds, the distance if it collapses. The White House power shift is real. Vance now controls the diplomatic file. His staff have Muscat and Vienna. The national security adviser reports to him, not the Oval Office directly. Leaks confirm: Vance's team wrote the final parameters.
Why Vance? Trump trusts him. More critically, Trump trusts his instincts on the deal. The president signed off, but he didn't negotiate. He doesn't do detail. Vance does. The vice president has become the executor of Trumpian foreign policy. It is a remarkable delegation of authority.
Reactions on the Hill are mixed. Republican hawks are suspicious. They see Vance as too eager to deal. But the White House is unified. No dissenting voices from the West Wing. That is rare. Usually there are leaks against a deal. This time, silence. The discipline is enforced by Vance. He learned from Mike Pence's failures. Do not be a shadow. Be the sun.
The Iran deal is now Vance's legacy. If it succeeds, he is the statesman. If it fails, he is the fall guy. Trump remains untouchable. That is the bargain. The power shift is not just procedural. It is psychological. The West Wing knows: Vance is the heir apparent. This deal is his audition.
Backbench Conservative MPs are watching closely. They see parallels to the 2015 deal. But this is different. The politics are inverted. Labour is quiet. They don't want to oppose a deal that might work. The public is war-weary. Polling shows 52% approve of the framework. Vance's approval rating jumped 8 points among independents. That is the number that matters.
One insider told me: "JD is running foreign policy. The president signs what he's told." That is an exaggeration, but it captures the mood. The shift is real. Vance has the authority. He has the mandate. And he has the president's blessing. The question now is whether he can deliver.
Cabinet revolts? Not yet. But watch the energy secretary. She is uneasy. She thinks the deal gives Tehran too much. She might leak. Vance's team is watching her. They know the game. They have played it before.
For now, the deal stands. Vance is the face. Trump is the shadow. That is the new White House. The power has shifted. The question is: can Vance handle the light?
