Istanbul Nuclear Summit Set: Witkoff-Araghchi Meeting Scheduled for 6 Feb 2026

Great-power coercive diplomacy has cycled like this before: in October 1962 Washington paired a naval quarantine with back-channel talks to defuse the Cuban Missile Crisis; and in 2013-15 the U.S. coupled sanctions pressure with secret Oman talks that birthed the JCPOA. Trump’s simultaneous saber-rattling and willingness to negotiate echoes those episodes, but today’s landscape is more multipolar—regional powers (Türkiye, Qatar, Saudi Arabia, UAE, Egypt) insist on seats at the table, reflecting a decades-long drift from U.S.–Iran bilateralism to a web of middle-power brokerage. The meeting matters because it could reset a confrontation that since 2018 has produced ever-shorter escalation loops, culminating in the 2025 12-day war and the deadliest Iranian domestic unrest since 1979. Over a 100-year horizon, whether this summit yields a durable framework or merely another pause will signal if nuclear restraint regimes can still be forged by pressure-plus-dialogue, or if the non-proliferation architecture that began with the 1968 NPT is entering irreversible decay.
