As as to be said somehow literally every time these headlines are published, nominations for any Nobel prize are kept secret and announcing that you've submitted a nomination if anything makes them less likely to be accepted as it harms the nomination by harming the image of the nominator. Anyone can say they've nominated anyone for a Nobel Peace Prize and they can't be proven or disproven for 50 years.

Oh and "Pakistan" can't nominate anyone for a Nobel Prize. All you need to be a nominator for the Nobel Peace Prize is to be an elected official or a university professor, but you do have to be a person. The likely of a headline not bothering to distinguish between a person and their 250 million people nation seems to increase linearly with distance east from the Greenwich meridian.

Please remember this when that Norwegian 'scientist' nominations Trump or Elon or whoever in October like he does every year.
