And of course if we’re speaking about Mr Churchill’s attitude to race we have to be a bit selective unless we want the full range of his views:
In 1937, he told the Palestine Royal Commission: "I do not admit for instance, that a great wrong has been done to the Red Indians of America or the black people of Australia. I do not admit that a wrong has been done to these people by the fact that a stronger race, a higher-grade race, a more worldly wise race to put it that way, has come in and taken their place."
Following the Indian Famine of 1943 he managed to secure huge supplies of Australian grain for Europe, but deliberately by-passed the starving Indians. He went so far as to suggest the famine was partly their fault as they “breed like rabbits”.
Of Mahatma Ghandi’s threatened hunger strike in pursuance of his dream of an independent India he said "Gandhi should not be released on the account of a mere threat of fasting," Churchill told the cabinet on another occasion. "We should be rid of a bad man and an enemy of the Empire if he died."
He had strong views on Islam, too: "How dreadful are the curses which Mohammedanism lays on its votaries! Besides the fanatical frenzy, which is as dangerous in a man as hydrophobia [rabies] in a dog, there is this fearful fatalistic apathy.
"Improvident habits, slovenly systems of agriculture, sluggish methods of commerce and insecurity of property exist wherever the followers of the Prophet rule or live."
So when he spoke of a “United States of Europe” we need to understand that the world (and public attitudes) was a very different place during his lifetime and his dreams may not quite be what we imagine today.
