If integrity requires a "devil's bargain" then I suspect you aren't the kind of person that really represents the values of the United States and hence you have no business being in a position of authority. There is nothing glib or sanctimonious in saying
WE WILL NOT TORTURE NO MATTER THE COST.
Because that is completely consistent with the values upon which this nation was founded. Unless you find glib the sentiments of Patrick Henry, Nathanial Hawthorne, Ben Franklin and the rest of the signatories of the Declaration of Indepenence, then your accusation of "liberal hypotheticallness" rings hollow.
For this liberal, its not hypothetical at all. I am a 1st generation American. My family has suffered at the hands of governments who were all too willing to sacrifice the rights of the people in the name of national security:
- My great uncle was summarily shot by a firing squad and buried while still alive
- My maternal grandfather was tortured to death for being a "national security risk' - because he editted a book of the collected works of the president of Latvia
- My grandmother and mother were placed in a forced labor camp because as DPs they were "undesirable". Their escape is nothing short of miraculous
- My father and his brother were strafed by an allied airplane even though they were clearly kids. They lucked out and froze up as the bullets walked by on either side of them
Growning up, the thing my dad kept reminding me was that America is DIFFERENT because the basic rights of ALL people are protected by the Constitution.
So to remind you of the words that those "glib liberals" I mentioned earlier used to describe what sacrifice is in keeping with American Values:
Give me Liberty or give me Death
I regret I have but one life to give for my country
Those who would sacrifice any of our precious liberties for a temporary measure of security, deserve neither security nor liberty
We pledge Our Lives, Our Fortunes, and Our Sacred Honor
I'll leave it to the interested conservative to look up which "liberal" said which or those phrases.
