Let me explain it to you as simply as I can, so you can follow the thought.
Goering thought that (1) people were no better than sheep and that (2) communism, fascism and representative republics were identical.
Therefore, according to Goering's line of thinking, no one ever thinks of war as necessary or serving a larger good and that people, as sheep, have to be herded into war through propaganda and groupthink. The idea of intelligent discussion and informed consent never enters his mind.
Your analysis of our current situation is identical to Goering's: the American people are sheep, none of them would ever have thought of the Iraq intervention as necessary and that support for intervention is purely a result of propaganda and groupthink pushed by an elite indistinguishable from communists or fascists.
My analysis is quite different: a large percentage of the American public were of the informed and considered opinion that it was unwise to have stopped our 1991 campaign at the Kuwait border. The American people have a participatory government and the majority of their elected representatives voted for intervention - knowing full well that if their vote upset their constituents many of them could be voted out of office in a matter of months. The American military, unlike the military of your hero Goering's experience, is a volunteer force and does not consist of mindless, dragooned peasants but professionals.
Therefore I am, as always, in utter disagreement with Goering's repulsive worldview, the worldview which you have adopted as your prism for the Iraq intervention.
