I hesitated to respond to this post because I thought it was made in jest, but it seems you never know with posts on PNGScape. So I'm assuming you are being serious with most of what you said, except of course for the impractical suggestions such as shooting people.
I would be interested to know how a "United" PNG is superior to a Federal PNG? Think of it this way...
If during colonial times, the Europeans had decided, on a whim, that PNG, Vanuatu, and Solomon Islands were one country called NueveEuropa or some such name, and we today were convinced that NE was better left united than separated even though it was logical to give greater autonomy to the different countries (given the diversity of the peoples, administrative capabilities etc..), would such a situation make sense? Do you think NE would be properly managed from Port Moresby,(or Honiara, or Port Villa)?
The same logic can be applied with the PNG situation. We cannot properly control the rest of the country from the centre because the whole of PNG is so diverse. Attempting to do so has led to the problems we continue to run in, but just like a man who thinks he can break a brick wall if he just continues to knock his head against it, we continue to insist on preaching the virtues of unity, even though we do not know what these virtues are.
To sum it up: Federalism is a must, if someone thinks that PNG is better controlled from the centre, he must present reasons why this is so.
I like some of your ideas about morality & that.
