Iran may reconsider nuclear doctrine if faces threat

Tehran may reconsider its nuclear doctrine if it faces an existential threat, the foreign affairs adviser to Iranian Supreme Leader Ayatollah Ali Khamenei, Kamal Kharrazi told the Financial Times.

"Up to now, we have not decided to go further than 60% enrichment. But we have been trying to expand our experience by using different machines and different set-ups," Kamal Kharrazi said.

He stressed that Iran is not for building nuclear weapons. But, according to the official, if Iran faced an existential threat, Tehran would have to change its doctrine.

Kharrazi noted that had the West triggered "snapback" provisions to reimpose UN sanctions lifted when Tehran signed the deal, in response to Iran’s continued expansion of its program, "there would be a severe reaction from Iran in terms of changing its nuclear strategy."
