Iran is equally non hostile to US and Israel the Muallah regime of Khomeni and now Khameni barb on daily basis to keep their power structure intact, the overall strategy of Iranian armed forces is passive and focusing on defending their land from aggression.i personaly conclude that Iran is not hostile to any Arab yes but against Israel and US. Its Arab world that thinks so and try to get Iran become hostile by giving US bases and open support.
spot on Man then the balance can only be maintained by the survival of Ayatollah regime in Iran-------- no attack on Iran ?US is using foolish Arabs to its advantage. US strategy (at present) is to balance sunni-shia influence while pretending to take side of the Arabs.
