Executive Tyranny and the Subversion of Constitutional Government

"The constitution vests the power of declaring war in Congress; therefore no offensive expedition of importance can be undertaken until after they shall have deliberated upon the subject and authorized such a measure." – George Washington, 1793. 

The cult of the executive and imperial presidency favored by the Democratic and Republican parties is perhaps the single greatest threat to constitutional government in the United States.  Today, the lawlessness of the presidency is matched only by the fecklessness of the Congress.  From Talking Points Memo:

The White House would forge ahead with military action in Libya even if Congress passed a resolution constraining the mission, Secretary of State Hillary Clinton said during a classified briefing to House members Wednesday afternoon.

Clinton was responding to a question from Rep. Brad Sherman (D-CA) about the administration's response to any effort by Congress to exercise its war powers, according to a senior Republican lawmaker who attended the briefing.

The answer surprised many in the room because Clinton plainly admitted the administration would ignore any and all attempts by Congress to shackle President Obama's power as commander in chief to make military and wartime decisions.

Is this not the very definition of tyranny?  The executive refuses to recognize any constitutional limitation of its power, and the Congress refuses to exercise its constitutional authority to limit the power of the presidency.  Such collusion amounts to nothing less than the outright subversion of Constitutional government.
