Those calling for international intervention in Syria should note that other countries are already involved -- although stabilizing the situation may not be their first priority. While the Saudis arm the Sunni-dominated rebels, the Iranians support the old Assad regime. According to the JCPA:

Iranian assistance to the repression of the Syrian uprising, which has included consultation as well as guidance in the “field,” began shortly after the protests first erupted. This aid was soon reported by Iranian opposition elements,11 who claimed that the repression in Syria was being carried out by a Syrian contingent of the IRGC-QF that had been operating in the country, and had been responsible over time for military, intelligence, and logistical assistance to Hizbullah in Lebanon. With the outbreak of protest in Syria, the IRGC-QF dispatched special emissaries, commanders of the Basij (volunteer forces of the IRGC-QF that also put down the uprising in Iran), to Damascus to help Assad.12 Other reports claimed Iran had provided Syria with logistical equipment, sniper rifles of its own make, and advanced Nokia Siemens Networks (NSN) devices for disrupting Internet activity, which allow the identification of activists who converse by phone or use the social networks on the Internet.13
