What thrust us into war were not Hitler's political teachings: the cause, this time, was his successful attempt to establish a new economy. The causes of the war were: envy, greed, and fear.

To me our bombing policy appears to be suicidal. Not because it does not do vast damage to our enemy, it does; but because, simultaneously, it does vast damage to our peace aim, unless that aim is mutual economic and social annihilation.

In the World War [WW1] nothing was more dreadful to witness than a chain of men starting with a battalion commander and ending with an army commander sitting in telephone boxes, improvised or actual, talking, talking, talking, in place of leading, leading, leading.

The strongest army in the world [the French] facing no more than twenty-six [German] divisions, sitting still and sheltering behind steel and concrete while a quixotically valiant ally was being exterminated!

National armies fight nations, royal armies fight their like, the first obey a mob, always demented and the second a king, generally sane.

An Army is still a crowd, though a highly organized one. It is governed by the same laws, and under the stress of war is ever tending to revert to its crowd form. Our object in peace is so to train it that the reversion will become very slow.

As the aeroplane is the most mobile weapon we possess, it is destined to become the dominant offensive arm of the future.
