The only government that "disintegrated" because of the starvation blockade was the Weimer Republic, albeit fourteen years lafter. It never recovered from the humilitiation of the peace treaty, which it had foolishly thought would be based on the 14 points (translated and airdropped before the Armistice). The pro-democrats were already in power in Germany by the time of the Armistice but the starvation blockade (condemned by the likes of Herbert Hoover and even British troops on the Rhine who thought starving German children was bad pr) continued for eight more months!
BTW, the mass slaughter of babies in their cribs and Japanese Christians in Nagasaki didn't accomplish anything. Truman received a surrender deal (e.g. the Japanese could keep the emperor) he probably could have had even before the bomb.
I am in the camp that blames FDR for this unconditional surrender notion and believe his surprise announcement at Casablanca resulted in the unnecessary deaths of millions of people and made the use of two atomic weapons inevitable. Great men at the time of that little act of self aggrandizement thought the worst of it and predicted many would die as a result. Churchill, in order to preserve the appearance of Allied unity, grudgingly went along with it – after the fact – and it proved to be poor judgment. Stalin thought FDR a madman for it.
Truman could have reversed FDR’s foolishness, but for the political price he thought he would have to pay to do so. While Nagasaki “accomplished nothing” neither did the firebombing of Tokyo, the bombing of Dresden, nor Sherman’s march to the sea. All were employed in a desperate effort to end bloody wars. Had Japan not raped Nanking and bombed Pearl Harbor, those babies in their cribs and Japanese Christians would have been spared. Who are you to judge through the lens of retrospect, accusing only American efforts, any unconditional force used to bring that war to an end? Nobody at the time had all the facts you believe you have.

He needed to end it right away so the Russkies wouldn’t tear themselves off a piece.
