Chesterton refererred to by Winston Churchilll

Winston Churchill referred to GKC in his book A Traveller in War Time.

Here is the passage:

America must now contribute what Britain and France, with all their energies and resources and determination, have hitherto been unable to contribute. It must not be men, money, and material alone, but some quality that America has had in herself during her century and a half of independent self-realization. Mr. Chesterton, in writing about the American Revolution, observes that the real case for the colonists is that they felt that they could be something which England would not help them to be. It is, in fact, the only case for separation. What may be called the English tradition of democracy, which we inherit, grows through conflicts and differences, through experiments and failures and successes, toward an intellectualized unity,--experiments by states, experiments by individuals, a widely spread development, and new contributions to the whole.
