Karma and Yeah this is for you -<quoted text>
Congress has the power to declare war, but no Constitutional power to "authorize use of force"...
Definition of war is a state of armed conflict between different nations or states or different groups within a nation or state.
An authorization for use of military force is a euphemism for war.
No constitutional scholar, that I am aware of, has ever claimed that a POTUS went illegally to war using "authorization for use of force..."
