Sadly the organizations of the UN are worse in effectiveness, ego, fraud, nepotism, and abuse. They even manage to grace these pages in shame. WIPO anyone? And the individuals? Usually either sent to the UN due to incompetence, but connected, corrupt, but connected. Occasionally we get lucky and get some member of a effective opposition, but connected!, who has been shuffled out of their country.
Then there's the anti-organizational goal bias. The very people that lobby to be accepted on a particular organization are those completely opposed to that function functioning. Look to the UN Human Rights commission. It's a those who of human rights violators and the ITU has just a bias as is, also gracing these pages.
Yet for all that, it might actually work, for certain definitions of work. And given that the ITU is positively salivating at the thought, it's an effective hydrogen bomb compared to ICANN's big stick.
