ELI5: How did the world clean up in the aftermath of World War II?

In the utter chaos and destruction that was World War II, how did the world and it's governments clean up and return to normal? (Or some *form* of normal.)

Three main points

1. Economic recovery. The US economy actually benefited from the war, because higher levels of investment in manufacturing increased output and productivity. Europe, however, was destroyed. The Marshall Plan of 1948 gave huge loans to western European countries (those behind the Iron Curtain were effectively forbidden from taking the loans by the USSR), which helped them to rebuild and get back on the path to economic prosperity. The UK only finished paying it's loans back to the US in the early 2000s.

2. Demobilisation. Countless soldiers had to be discharged. This was often a messy business, because jobs and homes simply weren't there waiting. The GI Bill was meant to solve some of these problems.

3. Political readjustments. Germany was occupied by France, the UK and the US for several years, until the three zones were combined into West Germany. De-Nazification had to occur, whereby anyone running for government positions had their background checked to make sure they hadn't been complicit with the Nazi regime.
