Lord Ponsonby's Ten Commandments of Wartime Propaganda:

1. We do not want war
2. The other side is solely responsible for the war
3. The enemy has the face of the devil (or in the order of “ugly”)
4. The real aims of the war must be masked under noble causes
5. The enemy knowingly commits atrocities. If we commit blunders, they are unintentional
6. We suffer very few losses. The enemy’s losses are enormous
7. Our cause is sacred
8. Artists and intellectuals support our cause
9. The enemy uses illegal weapons
10. Those who question our propaganda are traitors
