The idea here is how powers are split between levels of government. National defense, interstate commerce, and foreign policy require a single, unified approach across all states and with other nations, so they fall under the federal government. A centralized authority can maintain a national military, negotiate treaties, and regulate trade that crosses state lines, ensuring consistent rules and national security. In contrast, state governments typically handle matters like education, state courts, and intrastate issues, while local governments manage city or county services. This arrangement lets the federal level handle issues that affect the country as a whole, including defense, cross-border commerce, and international relations.
