<<So the idea is strong in concept but poorly implemented.
<<Perhaps the problem is with so many layers of authority, no one is accountable.
<<Maybe with some fine tuning and tinkering and plenty of encouragement for meaning well they will move it a littlle closer to reality.>>
That's pretty much the size of it. Like the UN itself, this is a 20th Century idea, meant to do away with the practices of thousands of years. Both of these ideas ultimately represent a very primitive form of world government, or at least of a world governed by laws. There's a very long road ahead, and you have to expect a lot of set-backs. That's what I meant by two steps forward, one step back. The fine tuning and tinkering etc. go with the territory. This is a project that will never be completed in my lifetime, but I think every fifty years or so, people looking back will see some small progress.
In regard to your crack about moving it "a little closer to reality," I think it's the supporters of Article 5 who are the realists - - they know how difficult the way forward is going to be, how many set-backs they will encounter, and how slow the overall progress will be, they are the ones who don't have any expectations of dazzling progress or brilliant successes. Those who need to "move closer to reality" are those who ridicule Article 5 and the campaign against torture generally for its ineffectiveness and lack of visible progress.
