In a recent incident, US national security adviser Mike Waltz mistakenly added journalist Jeffrey Goldberg to a private Signal group discussing potential military strikes in Yemen due to a phone contact error. The error was caused by an auto-save feature on Waltz’s iPhone, leading to a White House investigation. Despite the absence of leaked classified information, the situation upset President Trump. However, he chose not to dismiss Waltz in the end. This incident highlights the importance of caution when handling sensitive information, especially in high-ranking government positions. It serves as a reminder of the potential risks associated with technological mishaps in the modern age.
