The US airman who leaked classified Pentagon documents revealing US spying on allies and doubts about Ukraine's military strength has been sentenced to 15 years in prison. Jack Teixeira, 22, posted the sensitive documents on the social media platform Discord, reaching 150 million people worldwide. Teixeira pleaded guilty to federal counts of willful retention and transmission of national defense information. The leaked documents highlighted US concerns over Ukraine's military capacity and revealed apparent spying on allies Israel and South Korea. Teixeira's defense team argued for a minimum sentence, citing his autism diagnosis and ADHD condition.
