For our armed forces and intelligence services, torture may be a tactic. For our Muslim enemies, it is a strategy. That is a big difference ---and one that's ignored by the craphounds in Big Media.
The problem with John McCain or anybody else trying to recodify the various techniques our military and intelligence personnel use against our enemies is that it appears to take even the threat of torture off our table. But you can't tell your enemies what you won't do. That's a stupid policy.
