How does the confederal system differ from that of the US today?

A confederal system is characterized by a loose alliance of independent states that delegate limited powers to a central authority, which often lacks the ability to enforce decisions or tax directly. In contrast, the United States operates under a federal system where power is divided between the national and state governments, with the federal government having significant authority to legislate, tax, and enforce laws. This federal structure allows for a stronger national governance compared to the weaker, decentralized nature of a confederation. Thus, while confederations emphasize state sovereignty, the U.S. system balances state and federal powers more robustly.
