I say Trump has actually earned the Nobel peace prize. Especially in comparison to O'bama who did essentially nothing. I've no source, but I recall him remarking he wasn't sure what he did to merit the award. Trump's action, on the other hand is similar to what Teddy Roosevelt did to broker peace between Russia and Japan ca. 1903 = "Stop fighting, or I'll bang your heads together until you see things my way!"
The link discusses reasons why the Nobel committee awarded it to Obama. Spoiler alert: pretty much nothing - no dialog with countries in conflict or outlining a plan for peace in troubled regions.
