Every country has independent policy towards another country. Iran was a threat to India when Shah was running Iran because he supplied arms to Pakistan during India-Pakistan war. At that time Shah was ally to U.S. At that time U.S. gave whatever nuclear technology Shah wanted. Except Shah U.S. does not find any friend in Iranian total population. Similarly according to U.S. a country or a person is terrorist if it attacks U.S. or Israel. This is proven from the book written by Mr. Advani in which he wrote that U.S. declined to help India to get Dowd Ibrahim from Pakistan. U.S. policy is getting less relevence nowadays. So do not worry.
