Food for thought

I'm going to intercept this blog from time to time with what I think are relevant/interesting quotes from authors I have read.
So here is the second one folks.

• 'We cannot conclude from the good intentions of a statesman that his foreign policies will be either morally praiseworthy or politically successful'

• 'How often have statesmen been motivated by the desire to improve the world, and ended making it worse? And how often have they sought one goal and ended by achieving something they neither expected nor desired?'

• 'The demonological approach to foreign policy strenghtens another pathological tendency, which is the refusal to acknowledge and cope effectively with threatening reality'
