Ceasefire countdown begins: What happens if US-Iran talks don’t resume in time? |Mojtaba, Trump, War

A ceasefire is holding, but for how long? After 21 hours of negotiations in Islamabad failed to deliver a breakthrough, the United States and Iran are staring at a narrowing diplomatic window. With an April 21 deadline looming, the real story isn’t just whether talks resume, it’s what it will take to make them work this time. Why is Iran pushing for JD Vance to lead negotiations instead of Donald Trump’s trusted envoys? What does it signal when both sides walk in with maximalist demands? And is this deadlock actually part of the process, rather than a failure? From the collapse of the JCPOA to threats in the Strait of Hormuz, the stakes are no longer theoretical. Military options - from airstrikes to special operations - remain on the table, even as Pakistan, Turkey, and Egypt scramble behind the scenes to revive diplomacy. This isn’t just a negotiation over nuclear limits. It’s a test of trust, leverage, and political survival on both sides. So the question is: are these talks failing… or just beginning?
