Teixeira took an oath to defend the US and its military secrets, which are vital for US national security and the physical safety of personnel serving overseas. Teixeira violated that oath almost daily for a span of a year, committing one of the most serious breaches of the Espionage Act in American history. Teixeira was sentenced to 15 years in prison for his actions, sending a stern warning to other potential leakers.
Teixeira's actions, while wrong and misguided, stemmed not from malice but from a desire to connect with friends he had made online due to his autism. He is a youthful offender who has his whole life to look forward to. It would be more than sufficient for him to mature and bear the consequences of his actions, for which he has already acknowledged responsibility.
