What are US proposals to end war, and will Iran agree to them?

Iran is reviewing a United States peace proposal that would formally end the war, but leave unresolved key US demands including Iran's nuclear programme and the reopening of the Strait of Hormuz. The proposal reportedly includes a 14-point document where Iran would agree not to develop a nuclear weapon and halt uranium enrichment for at least 12 years. The US would lift sanctions and release frozen Iranian assets in exchange.
