Which power is exclusively held by the federal government under the Constitution?

The power to declare war is exclusively held by the federal government under the Constitution. This authority is outlined in Article I, Section 8, which states that Congress has the power to declare war. This power is centralized at the federal level to ensure that decisions regarding war and national defense are handled uniformly and with the consideration of the entire country's interests, rather than being left to individual states, which may have differing priorities or capabilities.

Establishing hunting and fishing laws, issuing driver's licenses, and setting education standards are powers typically reserved for state governments. These areas of governance are more localized and are often better managed by state legislatures that understand the specific needs and conditions of their respective populations. By reserving the power to declare war for the federal government, the Constitution ensures a cohesive and coordinated national response to external threats.
