<<Basically, your first line implies that you have a hard time finding men of honour in the U.S. military.>>
Yes, they've consistently disgraced themselves since Viet Nam.
<< Also, with no reference to the rest of what you said (I admit, I'm very naive about some of this) what is it you find inevitable?>>
I was speaking mid- to long-term of the inevitable rise to power of a fascist government in the U.S.A., towards which the current Bush administration has taken several giant steps, not the least of which is the legitimization of torture.
<<Off the top of my head, I believe that if I had military knowledge and were asked to speak to the Congress, I would. I would NOT, however, release any information regarding current state of affairs, or release any information that would/could be used against the United States. >>
As far as you are concerned, the U.S. Congress IS the United States. They are the democratically elected representatives of the people of the United States. If the executive branch has any objection to your speaking, they (through your superior officers) can forbid you to speak, and if Congress has the balls, they can challenge that order in court on various grounds depending on circumstances, in which case the court will decide.
It is not really your decision as to what information you will or will not give to Congress. If they ask, you tell. If ordered not to tell, you obey the order. If Congress challenges the order legally, you await the decision of the Court. Despite all the best efforts of the Bush administration, you still live in a nation of laws, not a nation of individuals each making his or her own law for himself or herself.
<<But if they wanted my opinion on topics I could discuss, I would. I would like the "leaders" of our country to be as informed as possible, while maintaining a "need-to-know" status on the security stuff.>>
As I said, it's not really up to you.
