If the examples springing to mind were in 1945 then that says a lot about how US efforts are going in the modern era. There is no real comparison to how the US handled defeated powers in WWII and how the State Department handles regime changes from ... I want to say the 60s onwards. All the people involved in Germany or Japan's reconstitution are dead (Ed Deming, we miss you; heros of the peace are the most impressive ones).

Which is a shame because the 1950s strategy of investment and prosperity made the world much better and the modern strategy of destabilisation tends to make it worse.

The modern Balkans seem better now than they were at the early ‘90s.
