The US has struggled to get Iran's bordering countries of Turkey, Pakistan and Iraq, particularly to close border crossings with Iran, as the decision could harm them more than the potential decision by Iran.
Iraqi officials have advised the US that the surveillance could spark unrest from militant groups along the Iranian border, which the Iraqi government does not fully control due to its rugged and mountainous nature.
The US ambassador to Turkey and regional envoy Sarif held weekly talks with Iraqi officials about damage to its border with Iran. Iraq refused the request but temporarily closed one or two border crossings as a symbolic gesture.
