Israeli journalist Amichai Stein reported via his political channel that the last U.S. proposal forwarded to Iran before the attack demanded Tehran halt support for proxies including Hezbollah and Hamas, and replace the Fordow fuel enrichment facility and every other functioning facility with alternatives that do not allow enrichment, according to a post shared over the past 90 minutes from 8:47 p.m. to 10:16 p.m. UTC on December 17. The announcement on Stein's 'ืืขืจืืฅ ืืืืื ื' channel, distributed via Telegram and WhatsApp, stated the proposal included these specific demands alongside other terms. No additional details or responses from U.S. or Iranian officials were reported during this period.
