Reports suggest that Waltz's deputy, Alex Nelson Wong, is also exiting his role, further indicating a reevaluation of the current national security framework. Last month, Waltz took the blame for the incident where Jeffrey Goldberg of The Atlantic magazine was mistakenly added to a confidential military discussion on the app. While both President Trump and intelligence leaders downplayed the incident, dismissing the security threats, the reaction from various political quarters called for a deeper inquiry into the situation. Democrats and some Republicans emphasized that what occurred could represent a serious breach of security protocols.

As Waltz takes "full responsibility," this exit may represent a larger issue amidst ongoing scrutiny of the communication methods employed by top officials in national security.

In summary, Waltz's resignation amidst a security debacle on Signal not only signals trouble for current U.S. national security protocols but also calls into question the reliability of communication methods among key leaders.
