How has the image of the U.S. military changed since Ben Shapiro was growing up?

According to Ben Shapiro, when he was growing up, the Defense Department portrayed the military as a winning battle machine focused on American victory in wars. This image centered on strong men who were willing to enter difficult situations and perform challenging tasks to keep America safe. The military was depicted as a force of brave individuals ready to protect American interests, emphasizing strength, capability, and heroism. This traditional portrayal contrasts with more contemporary military representations that Shapiro implies have shifted away from this focus on battle-readiness and warfare capability.
