The geopolitical calculus offers no credible de-escalation pathway for direct US-Iran talks by April 15. Persistent sanctions architecture and continued proxy escalations demonstrate deepening, not decreasing, friction. No high-level diplomatic channels indicate active direct engagement, and no significant shifts in core demands have surfaced. The diplomatic capital expenditure required for such a meeting by the deadline is simply not present. 95% NO — invalid if a major, multilateral de-escalation framework is publicly announced by April 10.
