Well... so long as were are prepared to accept such treatment of out own troops if captured, no problem.
If that was all our troops had to look forward to as
prisoners......not beheadings, or being emasculated,
or hung from bridges and set on fire.
Terrible things are going to happen to our troops in any case, so there is no signficiant down-side if we do at least some of these things to our own prisoners.
If people are really satisfied with this argument, in appears likely that nothing I can say (or more to the point, nothing thats said by members of the US military who also question these tactics) is likely to change their minds.
