Direct, high-level US-Iran diplomatic meetings by April 15 are a non-starter. The current sanctions regime and Iran's escalating nuclear file preclude immediate face-to-face negotiations. While Track-II channels and indirect messaging persist, overt, substantive diplomatic engagement leading to a formal 'meeting' within this short window is absent. Neither side has signaled the requisite political capital expenditure for de-escalation sufficient for such a summit. Sentiment: Public rhetoric remains confrontational, confirming entrenched positions. 95% NO — invalid if a major prisoner exchange directly precipitates a high-level confab.
