A bit selective perhaps?
Mountbatten? Churchill? Wellington even.
Even De Gaulle.
Mountbatten .....................inept as a politician, questionable as a military leader who "alledgedly" sought to overthrow Wilson, would have he achieved any of this if his parents were not German / British royalty ?
Churchill............. Successful brilliant Wartime political leader but had significant failures as a Military man and lost trust of people in WW1, had WW2 not occurred he would be a footnote in History. Even during phoney war didn't have enough support among MPs. Should have retired as a politician in 45 rather than continuing.
de Gualle............Brilliant soldier in WW1, saw what way war would occur but sidelined within France, understood better the need for post war France and keeping Communists out of power, resigned early and had an opportunity to return to save nation. Overall a better soldier than politician.
