Chelsea Manning’s Leaks Changed How the Public Saw the Iraq and Afghanistan Wars

Chelsea Manning was a U.S. Army intelligence analyst in Iraq when she copied classified military and diplomatic files and sent them to WikiLeaks.

What she disclosed

The material included Iraq and Afghanistan war logs, State Department cables, detainee assessments and video of a 2007 U.S. helicopter attack in Baghdad.

Journalists and researchers used the archives to examine civilian casualties, battlefield reporting and diplomatic practice. The government argued that the disclosures violated security rules and created risks for individuals and operations.

Trial and sentence

A military judge convicted Manning in 2013 of multiple offenses, including Espionage Act violations and theft, while acquitting her of aiding the enemy. She received a 35-year sentence and a dishonorable discharge.

President Barack Obama commuted the prison term in January 2017 to time served plus 120 days. Manning left military prison that May after nearly seven years in custody.

Transparency and accountability

Manning said she wanted the public to understand the human cost of war and U.S. foreign policy. Critics maintain that an analyst cannot unilaterally decide to release classified archives.

Her case also became inseparable from her treatment as a transgender woman in military custody and later advocacy on technology, gender and state power.

The geek lesson

Access creates responsibility and power. Manning’s actions produced lasting public knowledge and severe legal consequences, ensuring that debates about whistleblowing, proportionality and classified systems remain unresolved.
