It would be very surprising if Iran does not invest all its efforts and tricks to shorten its reach to nuclear weapons, under the auspices of the talks," a senior defense official said to News 12, expressing their concern about what Tehran will do during this 60-day window.President Trump Visits Israel And Egypt After Gaza Ceasefire Takes Effect JERUSALEM - OCTOBER 13: U.S. President Donald Trump (L) holds hands and speaks with Israeli Prime Minister Benjamin Netanyahu at the Israeli parliament, the Knesset, on October 13, 2025 in Jerusalem.

Conversely, Iranian Foreign Minister Abbas Araghchi has said that Iran will begin negotiations on the nuclear issue "on the very day we sign the MoU," according to the report.The US's withholding of details in the agreement, reportedly out of concern that Israeli leaks could derail Friday's signing, points to the extent of the current divergence between Washington and Jerusalem on Iran, N12 reported.Iran to receive $300b. in cash after signing MoUThe sequence of events suggests that upon immediate signing of the MoU, Iran would receive sanctions relief and easing of fuel and energy trade restrictions.I would also get an estimated cash inflow of over $300 billion, with more than half reportedly already committed, according to Reuters.This would occur while Iran retains control of the Strait of Hormuz, and with discussions of Iran’s nuclear program to then begin.Follow us on Google
