Is the is the power to have a military draft an implied power of Congress?

Yes, the power to have a military draft is considered an implied power of Congress. While the U.S. Constitution explicitly grants Congress the authority to raise and support armies (Article I, Section 8), the ability to enact a draft is derived from this power as a necessary means to fulfill that responsibility. The Supreme Court has upheld this interpretation, affirming that Congress can implement a draft to ensure national defense and military readiness.
