Not all diplomatic and non-military options have been exhausted in dealing with the Iranian nuclear threat, former Mossad head Shabtai Shavit said in an interview with Army Radio on Sunday.
The ex-chief said he sees "encouraging signs in the American process" of dealing with the situation.
On Thursday, the US sanctioned three foreign companies doing business with Iran’s energy sector. The move followed additional tough sanctions the White House recently put in place against Iran, in an effort to convince the leadership in Tehran to abandon its nuclear program.
