" We must not take everything on our own shoulders; if we did, our successors would have nothing to do but to sleep. We must leave them some problems to solve, and the means with which to solve them—namely, a mighty Army and a mighty Air Force ; and the Army must be taught that, if some cowardly crew of politicians should come to power, then it is the Army's duty to intervene—as the Army in Japan did.
As a general principle, I think that a peace which lasts for more than twenty-five years is harmful to a nation. Peoples, like individuals, sometimes need regenerating by a little bloodletting. Our ancestors fought duels. Next came the barber and his bleeding-cups—and now we have the safety razor !
Nobody in the Middle Ages suffered from high blood-pressure—their constant brawls were ample safeguard against it; and in Upper Bavaria they practised the custom of Sunday bloodletting. Now, thanks to the safety razor, the world's bloodpressure is rising. It fills me with shame when I think that I have lost more blood shaving than on the field of battle. "
