Question

which constitutional principle prohibits an individual state from declaring war?
○ limited government
○ federalism
○ balances
○ popular sovereignty

Explanation:

Federalism divides power between the federal (national) government and state governments. Under the U.S. Constitution, the power to declare war is exclusively granted to the federal government, so states cannot exercise this power, which is a core feature of federalism. Limited government refers to restricting government power generally, balances (checks and balances) refers to power distribution among federal branches, and popular sovereignty means power comes from the people, none of which directly prohibit states from declaring war.

Answer:

federalism
