WASHINGTON -- The Islamic Republic of Iran would like to make one thing clear: We've got this. Up until June 10, Iranian officials had been content to shape events in Iraq quietly through their hold on local Shiite militias and the prime minister at the time, Nouri al-Maliki. Then the Iraqi government lost Mosul, the nation's second-largest city, to the growing Sunni extremist force now known as the Islamic State, or ISIS.
