Which entity is involved in the preparation, prevention, and response to domestic incidents?

The Department of Homeland Security (DHS) is tasked with coordinating and overseeing the preparation, prevention, and response to domestic incidents, which include both natural disasters and terrorist threats. This entity plays a critical role in national security by strengthening the nation’s ability to respond to various emergencies.

DHS works alongside state and local governments, law enforcement, and emergency services to ensure that comprehensive strategies and resources are in place to manage incidents effectively. Their focus includes establishing policies for public safety, conducting drills and training exercises, and facilitating communication among various agencies involved in emergency responses.

In contrast, the other entities listed have specific areas of focus that do not primarily involve domestic incident response. For example, while the Centers for Medicare and Medicaid Services oversees health care programs, and the Centers for Disease Control and Prevention focuses on public health and disease control, neither of these organizations is responsible for the broader aspects of domestic incident response that DHS handles. The National Institutes of Health primarily conducts medical research and does not engage in incident response in the way DHS does. Therefore, DHS is the most appropriate choice for coordinating responses to domestic incidents.
