Why is declaring war a delegated power?

Declaring war is a delegated power because it is specifically assigned to the legislative branch of government, typically the Congress or Parliament, as outlined in a country's constitution. This delegation is intended to ensure that such a significant decision requires broad consensus and representation of the public will, rather than being made unilaterally by the executive branch. The separation of powers principle reinforces this delegation, promoting checks and balances to prevent abuse of authority and to maintain democratic governance.
