Donald Trump has claimed responsibility for ending eight wars during his presidency, including conflicts between Armenia and Azerbaijan, Thailand and Cambodia, Rwanda and the Democratic Republic of Congo, Israel and Iran, Israel and Hamas, India and Pakistan, Egypt and Ethiopia, and Serbia and Kosovo. While some of these claims have been supported by peace agreements brokered with US involvement, experts note that many of the underlying issues remain unresolved and that some deals are tenuous or disputed by the parties involved.

Trump has repeatedly argued that his efforts to broker peace should earn him the Nobel Peace Prize, and several world leaders have nominated him for the award. However, the 2025 prize went to Venezuela's opposition leader Maria Corina Machado, prompting criticism from the White House. Trump remains a candidate for the 2026 prize, especially if his Gaza peace plan leads to lasting stability.

Despite his claims, critics and peace experts question whether Trump meets the criteria set by Alfred Nobel, citing his withdrawal from international agreements and controversial domestic policies. Some members of the Nobel Committee have suggested that Trump's active lobbying for the prize may actually harm his chances.
