Winston Churchill and two famous sayings
"A man who is not a socialist at age 20 has no heart; A man who is still a socialist at age 30 has no head".
Who said that? Most people attribute it to Winston but as far as I can tell it was first said by Georges Clemenceau, French Premier in WWI -- whose own career approximated the transition concerned. And he in turn was simply updating an earlier saying about monarchy versus Republicanism by Guizot.
More obscurely, I wonder about a saying attributed to Bismarck, the towering 19th century statesman who unified Germany and gave Europe over 40 years of peace thereafter. Bismarck is often quoted as saying that the next European war would arise over "Some damn-fool thing in the Balkans" - which it did of course. But did Bismarck actually say that? I have been able to trace it back only to Churchill as having quoted it.
German sites (e.g. here) have MANY collections of Bismarck quotes and nothing like it appears there. Bismarck did say that the Balkans were not worth the life of of a single German soldier (Der ganze Balkan ist nicht die gesunden Knochen eines einzigen pommerschen Grenadiers wert) so did Churchill embroider on that? I would be interested to hear if anyone knows anything more
