The Constitution empowers Congress alone to "declare" War.
The Constitution empowers the President as Commander in Chief of the Armed Forces.
The Constitution forbides the States from engaging in war unless actually invaded or in imminent danger of invasion.
The Constitution contains no language barring the Commander in Chief from engaging in war. Why? Because there was no intent by the framers to place such restrictions on the President acting as in his role as Commander in Chief. That's why.
SemperFiUSMC,
I need Clarification. Are you saying that though the Constitution says that Congress has the right to declare war, because it doesn't say the President can't declare war that he therefore can?
