Because of the war against terrorists, Secretary of the Navy England challenged the U.S. Navy to __________?

The correct response indicates the challenge posed by Secretary of the Navy England in relation to the evolving nature of warfare against terrorism. The U.S. Navy was prompted to focus on maintaining its relevance in an environment where traditional naval power might be questioned due to the asymmetrical nature of terrorist threats.

As the nature of conflicts shifted towards counter-terrorism and irregular warfare, the Navy needed to evolve its strategies, capabilities, and operational focus to ensure it remained a vital component of national defense. This entailed adapting to new roles that included not just traditional naval engagements, but also partnerships with land-based forces and operations tailored to counter-terrorism efforts.

While enhancing training programs, increasing recruiting efforts, and cutting unnecessary expenses are certainly important for maintaining an effective and efficient naval force, the overarching challenge emphasized by England was the imperative for the Navy to preserve its relevance in the face of changing global threats and operational requirements.
