I do not understand this squeamishness about the use of gas... I am strongly in favour of using poisoned gas against uncivilised tribes... It is not necessary to use only the most deadly gases: gases can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effects on most of those affected.
The main thing is this: we should never blame anyone or anything for our defeats. No matter how evil their intentions may be, they are altogether unable to harm us until we begin to blame them and use them as excuses for our own unbelief.
