"The same people who supposedly believe that using weapons of mass destruction is a crime against humanity. are talking about new weapons to threaten or use against rivals, " he added.
Iran is accusing the USA of threatening Russian Federation with the use of new nuclear weapons following the Trump administration's call to expand nuclear capabilities in an aim to deter Moscow, Reuters reported Sunday.
"The biggest difference relates to the supposed role of nuclear weapons in American military strategy", Michael Klare, an expert at the Arms Control Association, told Xinhua.
The US military has put countering China and Russian Federation at the centre of a new national defence strategy unveiled earlier this month, shifting priorities away from fighting Islamist militants.

Tangen also pointed out that nuclear deterrents can "blow up the world many hundred times over with the existing stockpile".
But that magical moment seems to be elusive - and at most, a political fantasy, particularly under a Trump administration. Martin Schulz, who challenged Angela Merkel last September, called for remaining American bombs to be removed from Germany. Top-diplomat also said: "Trump's obduracy in killing the JCPOA (Iran's nuclear deal with world powers) stems from unsafe imprudence".
