I cannot understand how any person of Christian faith can justify the use of lies and deceit, and bringing mental anguish upon a fellow human, as a defense of the christian way of life.
regardless of information that might be obtained, i see this as advocating evil and propagating it as well. Use of military power to go and get those who have physically attacked us is one thing, The use of torture (which is what these techniques are, no matter how you try to justify it) to further an offensive strategy, or try and prevent another attack from those who would wish you harm is blatantly wrong. And I believe it's an affront to the Lord.
There are so many other ways of getting intelligence without the use of evil acts, which i see as mimicing those who we are afraid of. ( The more we justify it, the further we are from God)
Just to pose a query, if you were driving along a crowded moutain pass, following a long line of cars, and you saw everyone ahead of you suddenly veer of the road and go off a cliff, would you do the same? No, because you know where it leads. Why would you advocate evil if you know where it leads?
IMO We don't belong where we are not wanted. Did the Apostle's continue to preach in cities or lands that would not listen or believe? No they left them for the Lord to judge. And i believe we should follow their lead.
