Undoubtedly, like almost every politician and us, a life of positives and not so proud moments.
But his relentless work against the genocidal National Socialists from 1933 onwards, when most of the rest of the nation and elsewhere thought he was a loon, plus his charismatic, cut through the red tape, leadership from 1940 to 1945 …. outweighs anything. Others would’ve thrown in the UK towel. How more tens of millions of Slavs, Jews, intellectuals, homosexuals and disabled would’ve been murdered or starved to death in that enduring Europe?
Oh I agree wholeheartedly with virtually everything there. What I think counts against Churchill during this period is his indifferent, many would say callous, attitude to the Bengal famine which tarnishes that period (only slightly mind). However I personally (with my historian hat on) am loathed to look at someone during a single period and make a judgement on them for that alone, when analysing Churchill the historical figure we also have to include his terrible handling of the Gold Standard debacle of the 1920s, his actions in South Africa around the turn of the century, and of course his flounce at failing to win the 1945 election he felt he deserved to.
