A group of about a dozen U.S. State Department officials have taken the unusual step of formally accusing Secretary of State Rex Tillerson of violating a federal law designed to stop foreign militaries from enlisting child soldiers, according to internal government documents reviewed by Reuters.

A confidential State Department “dissent” memo not previously reported said Tillerson breached the Child Soldiers Prevention Act when he decided in June to exclude Iraq, Myanmar, and Afghanistan from a U.S. list of offenders in the use of child soldiers. This was despite the department publicly acknowledging that children were being conscripted in those countries.[tmsnrt.rs/2jJ7pav]

Keeping the countries off the annual list makes it easier to provide them with U.S. military assistance. Iraq and Afghanistan are close allies in the fight against Islamist militants, while Myanmar is an emerging ally to offset China’s influence in Southeast Asia.
