The substance of Iran's 14-point peace proposal became public Monday May 18 via NPR / Al Jazeera reporting. Key points: 30-day end of war (vs the US-proposed 2-month ceasefire), guarantees against future US military aggression, withdrawal of US forces from Iran's periphery, end of naval blockade, release of frozen Iranian assets, payment of reparations, lifting of sanctions, end of fighting in Lebanon, new Strait of Hormuz mechanism. Tehran's framing: end the war and resolve the shipping standoff first, defer nuclear-program talks. Trump publicly characterized the proposal as "not acceptable" and said strikes could resume if Iran "does something bad" - the cancel-Tuesday-strikes move is procedurally compatible with rejecting the proposal substance while pulling back the kinetic near-term tail.
