Donald Trump says his latest Nobel Peace Prize snub left an “indelible stain on Norway”.
The prize Norwegian committee gave the award to Navanethem “Navi” Pillaya South African lawyer and former UN Human Rights Commissioner who once represented Nelson Mandela.
It said she was a “source of hope and inspiration to all who seek to bring about a more peaceful world”.
Mr. Trump but struck a very different tone, dismissing Ms Pillay, 85, as an unknown “liberal person” who “hates Israel”, as he again claimed he should win to settle “eight wars”.
The president has made no secret of his desire to win the prize, and was also critical when Venezuela’s Maria Machado won the prize last year.
They later gave her medal to Mr. Trump during a White House visit.
Writing on Truth Social, the US president claimed that “every president and prime minister” from the countries he helped had sent letters to the committee.
“Even with Iran, I stopped them from destroying Israel, the Middle East and Europe,” he wrote. “I also prevent, on a constant basis, a war between South Korea and North Korea, and Japan and North Korea.
“Add China and Taiwan, and many other hotspots that have not been involved in wars, only because of President Donald J Trump, and the United States of America.”
He added: “This is an indivisible stain on it Norwayone that will never be forgotten.”
Mr Trump said he was “close” to ending the Iran and Ukraine conflicts.
In a later post he said: “I have resolved 8 WARS, am nearing the end or 2 more to settle, returned all the Israeli hostages… had hundreds of hostages, from countries all over the world, released and sent back home, won a war in Venezuela, captured the violent dictator who ran that country so badly, and stopped the number 1 terrorist from Iran, sponsoring the Islamic State, Iran, the Republic of Terror – AND MUCH MORE!
“But, with all that, I, or the United States of America, did not receive the Noble Peace Prize. WOW!”
He made similar remarks at a midterm campaign rally in Syracuse on Friday, telling the crowd that the award would be “forever discredited” by not awarding it to him.
Hours after Ms Pillay was revealed as the winner, Mr Trump’s administration also announced sanctions on the International Criminal Court, for which she worked.
The United States has previously imposed sanctions on judges and prosecutors, but the latest move to “link transactions” with the “rogue court” means companies that provide services could also be fined.
The court called it an “assault on the rule of law and on the very foundations of the international legal order”.

Ms. Pillay’s victory is seen as a punishment for the US President, as well as the Israeli Prime Minister Benjamin Netanyahu.
Both leaders have both rejected the findings of a UN commission they led, which concluded last year that Israel was responsible for genocide in Gaza.
Israel has vehemently denied the claims, and refused to cooperate with the commission.
It said on Friday that giving her the award was a “grotesque weaponization of an award to legitimize anti-Israel hatred and prejudice”.
Ms Pillay has denied claims of anti-Semitism.
Who decides the peace prize?
The committee consists of five members chosen “to reflect the relative strengths of the political parties” in the Norwegian parliament.
However, the current MPs and government ministers are excluded.
The committee accepts nominations from people who meet certain criteria, including members of national governments and previous winners.
A shortlist of around 20-30 nominations is drawn up and advice is sought from a body of advisers, which the committee says “generally consists of a small group of Norwegian university professors with broad expertise in subject areas with an influence on the peace prize”.
Other experts may also be consulted before a final decision is made each October.
If all members do not agree, a majority vote is taken.
This year, 208 people and 79 organizations were nominated. Details of who was nominated, and by whom, were kept secret for 50 years.
