The United States has proposed a 20-year moratorium on Iran's uranium enrichment program during negotiations in Islamabad, Pakistan, according to Axios. However, Iran has countered with a request for a significantly shorter timeframe, creating a major sticking point in efforts to revive a nuclear agreement. The disagreement centers on whether Iran would halt enrichment entirely and relinquish its existing stockpile, which has emerged as a central obstacle preventing a breakthrough. The outcome of these negotiations is critical, as it could determine whether a fragile ceasefire holds beyond April 21. Mediators from Pakistan, Egypt, and Turkey are actively working to narrow the differences between the two nations. Despite the gaps, Iranian negotiators expressed optimism about reaching an initial agreement. However, tensions escalated following a press conference by US Vice President JD Vance, which indicated no imminent deal and placed blame on Tehran. Israeli Prime Minister Benjamin Netanyahu has been briefed on the situation, emphasizing the need to ensure no enrichment occurs in the coming years.
