Iran's President Hassan Rouhani said during a televised speech on Thursday that the United States' declaration that the Iranian Revolutionary Guards Corps is a "terrorist organization" is an "insult" to Iran."I want to tell the regional countries that the armed forces of the Islamic Republic of Iran are not against you and your national interests. They stand against invaders... The roots of our problems are the Zionist regime and American imperialism," Rouhani said during the ceremony in Tehran, which was broadcast live on state television.
