As Trump’s recent message said, he has claimed to have ended eight wars since his second term as president began last year.
The White House has previously listed these as conflicts between Israel and Hamas, Israel and Iran, Pakistan and India, Rwanda and the Democratic Republic of Congo (DRC), Thailand and Cambodia, Armenia and Azerbaijan, Egypt and Ethiopia, and Serbia and Kosovo.
BBC Verify has examined Trump’s claim which include a number of “wars” which had lasted just days, although were the result of long-standing tensions, and in some cases – for example Egypt and Ethiopia – there was no fighting to end.
There has also been fighting between Rwanda and the DRC, despite the two sides signing a peace agreement.
The peace prize was awarded to Venezuelan opposition leader MarÃa Corina Machado.
Later, when US forces seized and removed Venezuela’s president Nicolás Maduro from Caracas, accusing him of drug trafficking and other crimes, Trump did not endorse Machado as the country’s next leader and instead backed Maduro’s vice-president as the interim head of government.
Machado, who has praised Trump, met him at the White House last week and gave her medal to him. The Nobel Foundation had said the award could not “even symbolically, be passed on or further distributed”.
