Iran has been suspected of developing a nuclear weapon under the guise of a civilian program. The Israeli leader is among the most prominent opponents of the deal which would ease up sanctions against Iran in exchange for Tehran making its nuclear program more transparent.
According to the source, Netanyahu said during a meeting of the security cabinet it would be "impossible to catch the Iranians cheating simply because they will not break the agreement.”
The prime minister reportedly argued that the world powers would stop monitoring Iran's nuclear activities closely in 10-15 years after the deal is signed. Thus, Iran would have the chance to continue its alleged work on the development of a nuclear weapon.
Under the agreement, The United Sates, the European Union and the UN Security Council would partially lift their nuclear-related sanctions following a confirmation by the International Atomic Energy Agency (IAEA) of Tehran's compliance with the deal.
Last month, Netanyahu held a speech at the US Congress in an attempt to thwart the deal he says is dangerous for the Middle East security.
