@deech you sure that "getting things done" is a good metric?
If that were the case than certainly Germany from '33 - '45 is hard to beat.
- lots of Autobahns
- almost no Unemployment
- almost all of Europe conquered
- several million Jews and other murdered
- almost all of Germany's infrastructure destroyed
- millions of German soldiers dead or missing

... so somehow the overall effect was not exactly what was promised.

I agree that Americas democracy gets "more done"
