Do they now. Was this bought to you by Fox News? Iran fund the reprehensible republican guard, and have horrors like Ashraf on their hands, but Iran stick to Iran.
Yes, they do. Iran has a huge influence outside their borders.
Iran has been funding and aiding al-Assad in the Syrian civil war. Hamas was, for awhile, funded almost entirely by Iran. Hezbollah has also largely been funded and supported by Iran. There is evidence that Iran provided weapons to the Iraqi insurgency during the Iraq War.
