The Nobel Peace Prize lost all credibility when it was awarded to unrepentant former terrorist Menachem Begin, and Werner Von Braun, SS member who designed theV2 rocket for Hitler.
I would have argued perhaps from when Kissinger was awarded it with Le Duc Tho, and Le Duc Thorefused it, as there was still issues with the implemenation of the peace, and it highlighted the lack of commitment from Kissinger and the US? Von Braun never won the Oeace Proze though he had a number of other awards.
I think in this case the interesting thing is that some of the suggestion for awarding Trump the prize from the relatives of the hostages, has been to keep Trumo intetested. Perhaps an even more cynical view is to dangle it in front of him for another year?
The award to Obama, which seemed to be for being a black President of the US, means that any comment from the Dems on this against Trump looks partisan.
Leaving aside the flummery of the prize, I only hope that the negotiations are successful, and that Trump does remain interested in making sure the peace holds.
