Note to Sean Hannity and Newt Gingrich - It is George W. Bush and his needless war in Iraq that has emboldened the Iranians, not Democrats who voted to withdraw from the mess.
The Iranians sat back and laughed when Bush invaded and overthrew Saddam Hussein's Sunni dominated government and helped install a government of Shiites's who have deep loyalties to them.
If we didn't want to embolden Iran we should not have invaded Iraq. As the saying goes, the war in Iraq is over, and Iran won.
