The US airman who leaked classified Pentagon documents has been sentenced to 15 years in jail. Jack Teixeira, an IT specialist with the Massachusetts Air National Guard, posted sensitive documents on Discord, leading to their spread across the internet. Teixeira pleaded guilty to federal counts of willful retention and transmission of national defense information. The leaked documents revealed US concerns over Ukraine's military capacity against Russia and indicated that Washington had spied on allies Israel and South Korea. This breach raised questions about access to high-level secrets by junior staffers.
