No Place For Torture In a Just War
We have the rather unusual situation where a sitting US president publicly claims that torture is ethical, whilst his Secretary of Defense says it is counter-productive and of no use. James "Mad Dog" Mattis is reported as adopting a pragmatic position (implying that if were to work, he would endorse torture). President Trump says he will abide by Mad Dog's greater experience and wisdom in matters military and engaging in war.
This is hardly a satisfactory position. One can easily foresee a particularly gruesome terrorist attack on US soil with many deaths and casualties (think Twin Towers) and with evident extensive conspiracies attached (think 1605 Gunpowder Plot in England). Expect Donald Trump in fear and anger and frustration to order the use of torture out of retaliation and anger more than anything else, whilst justifying it by the supposed information it would reap.
The sad and unacceptable thing is that both Trump and Mattis appear to base their moral position on pragmatism, or, to put it in a wider philosophical context, on utilitarianism. It has long been a fatal flaw of that particular philosophy that the end most certainly does not justify the means. The Christian position is clear: both ends sought and means employed must be holy, just, and good. The West--particularly the Anglo-Saxon West--has suffered under the barren amoral wasteland of utilitarianism far too long.
