Writing in Kayhan, Shariatmadari argued that two decades of negotiations had failed to protect Iran’s nuclear facilities from attacks, saying that “remaining in the NPT no longer makes sense” and that Iran’s only option was to strengthen deterrence.
“Those who say that if we leave the NPT it will pave the way for an attack must answer two questions. First, did they not attack our nuclear facilities while we were in the NPT? Second, does not America insist that attacks on Iran’s nuclear facilities should not be prohibited? … So what are you waiting for?” he wrote.
The 15-member UN Security Council on Friday opted not to permanently lift sanctions on Tehran, after Britain, France and Germany launched a 30-day process last month to reimpose them, accusing Iran of failing to comply with the 2015 nuclear deal.
Shariatmadari dismissed the return of UN sanctions under the so-called snapback mechanism as “an empty shell” compared with US secondary sanctions.
“For years Iran’s economy has been under the pressure of Washington’s multilayered sanctions, which are far broader and harsher than the UN’s restrictions," he wrote.
"The snapback (mechanism) neither brings extra sanctioning power nor grants a fresh license for war,” he wrote.
Lawmakers warn of NPT pullback
Shariatmadari’s call was echoed by lawmakers who also warned Iran could scale back its cooperation with international nuclear agreements.
"We warn the countries that exploit Iran's goodwill for 'dialogue' and close the doors of diplomacy to themselves that 'maximum pressure' never works, and this time they will regret it harder than ever," said Ebrahim Azizi, head of Iran's National Security and Foreign Policy Committee.
Another lawmaker, Fada-Hossein Maleki, said the country was prepared to scale back cooperation with international bodies. "The Islamic Republic is prepared for any scenario, including withdrawal from the agreement with the International Atomic Energy Agency (IAEA) and even seriously considering withdrawal from the Nuclear Non-Proliferation Treaty (NPT)," he said.
