The United States and Iran are nearing an agreement on a Memorandum of Understanding (MOU) for war termination and nuclear issues, including a halt to uranium enrichment and sanctions relief. The negotiations are being mediated by Jared Kushner, Trump's son-in-law, and key issues include Iran's handling of highly enriched uranium and extending the negotiation period in case of agreement violations. Both countries plan to agree on basic principles first and then proceed with detailed cessation negotiations.
