The phrase signifies a hypothetical mass resignation of military personnel attributed to dissatisfaction with the actions or policies of a former U.S. President. It implies a potential crisis in military morale and confidence in leadership. Such a large-scale departure, if it were to occur, would represent a significant political statement and raise concerns about stability within the armed forces.
The importance of such an event lies in its potential impact on national security and the perception of governmental legitimacy. Historically, significant dissent within the military ranks has been a rare occurrence in the United States. If a considerable number of personnel were to leave their posts, it could signal deep-seated issues within the military culture or a profound disagreement with the political direction of the country. This could affect recruitment, retention, and overall effectiveness of the armed forces.
