Nice how you base your argument on the creation of The Department of Defense but conveniently forget that we have had a standing military protecting people like you since the foundation of our Constitutional Republic.  And no, we haven't won any wars since then.  Not because we couldn't have won them but simply because we haven't had a War to fight since the end of WWII, were our men and women in our military fought to preserve your rights.  Have we prevailed in the military actions we have undertaken since?  No, it's true that we have not.  But if you examine those actions from a historical view it was the hysterics of the liberal mind that fueled those losses.  But there are some wins, despite the incessant mindless whimpering of anti-military/anti-US liberals all across our nation today.  Yet we tolerate their freedom of speech.  Why shouldn't we?  Many died to preserve that freedom even though they disagree with their mindless and largely ignorant rants like yours.
