I think most if not all of you are not getting "the big picture", and seem to believe that the basic purpose of the exercise is to preserve and perpetuate what we loosely call "the American way of life".
IMHO, the real game is to instigate "one world government" whose goals and objectives are to "average out" the standards of living of everyone in the world, except for the elite. A very rough idea of the new "system" would be that graduates of whatever programs Harvard offers would be the elite with the rest of the indifferent populace being their semi-slaves, The new enemy of such a society would be what today we call the "conservatives".
It would be necessary to combat the forces of conservatism through control of the educational process, and by gradually legislating against the expression of conservative ideals. Peer pressure could be brought to bear to the extent that expressing a conservative opinion would be equal to uttering "the "N" word" today.
INMO , the Moslem based religions are an excellent vehicle for bringing to fruition these ideals, as they seem to do what they are told without question, and be very intolerant of contrary positions.
Back to the question at hand, a case can be made for being nice to those we capture, as some of them will "escape" "be deported" or declared political prisoners and freed, and eventually become part of our (or the world's) ruling class.
Anybody read Robert Bork's "Slouching toward Gommorah" or "The New World Order by Gary Kah?
No, I am not applauding any of these changes, but believe that they will likely come to pass.\
