At the recent Munich Security Conference, U.S. Secretary of State Marco Rubio emphasized the need for a reevaluation of U.S. foreign policy, stating, "the fundamental question we must answer at the outset is what exactly are we defending, because armies do not fight for abstractions. Armies fight for a people; armies fight for a nation." This marks a shift from Vice President J.D. Vance's earlier confrontational rhetoric, which had alienated allies. Observers noted that Rubio's serious tone was a welcome change, although Jonah Goldberg pointed out that his approach did not fully address the complexities of the current geopolitical landscape, particularly as European nations rely on U.S. military support while their own defense capabilities weaken.
