@MLClark: It is not possible for an permanent, ongoing international, national, or regional, often even local collaborative anything, and that's because of human nature and because humans don't individually live long enough... and those who do live long enough are either corrupt AF, apathetic AF, or not at all listened to by younger people because "you're old and don't what things are like now" or "you got us INTO this".
Hence "the more things change, the more things stay the same."
@MLClark: It's also why "here comes the new boss, same as the old boss".
Humans have egos and ids, and those are both good things and really bad things. Most people do not learn to balance them, and they confuse them with identity. Varying degrees of hilarity ensue.
