Although, as leader of the Conservative Party, Churchill can't really be expected to be an unbiased source on the subject...
He wasnt just leader of the Tories, he was son of the Duke of Malborough, his mother was MANY times a millionaire, he lead Britain into economic ruin as Chanc. of the Exchequer, was an alcoholic, rascist, stupid fat bastard...if the USA hadn't landed at Normandy, the USSR would STILL have crushed Germany, but Britain would most likely have become German in the meantime, cause Churchill just did not understand what he was being told day after day by his staff: you are sending our pilots/mariners/soldiers TO THEIR DEATHS as they are outnumbered by the Germans, who had superior technology AND training. In my view the guy had NO redeeming factors, he couldn't even do a decent V for victory without making it look like he was telling the cameraman to "Fuck off".
