@failures art,
Yes I would.
I'm not of the opinion that only America should get to use these "enhanced" techniques.
If another nation truly believes American captives pose the same threat to them as Al Qaeda members pose to us, then I would understand why they might employ these techniques on American captives.
Of course I don't believe this has ever been the case, but I can speculate for argument's sake.
At the same time, such nations must be prepared for the consequences of using such techniques on American captives, and not expect us to simply accept that our agents are the equivalents of Al Qaeda agents.
If Al Qaeda could punish us for using these techniques against its agents, they would have, and I wouldn't be crying "foul!"
The world has not, does not, and probably never will operate within legal strictures established by folks who's heads have taken up permanent residence with the theoretical.
The measure of the character of a nation is not whether or not it subscribes to the notion that might makes right, but whether it is mighty and yet demonstrates restraint.
