The United States announced a 60-day pause on some sanctions against Iran on Monday, potentially opening the door for billions of dollars in financial gains for Tehran. However, experts caution that reversing over four decades of sanctions is a complex undertaking. Significant legal hurdles, political obstacles, and commercial difficulties are anticipated. The reprieve does not signify a swift return to normal economic relations. Unwinding the extensive sanctions regime will likely require years of negotiation and implementation. The move signals a potential shift in US policy, but substantial challenges remain before Iran can fully benefit from eased restrictions.
