In time of war, you have to get people on your side, whether it is getting your own people to be willing to fight, or convincing allies that your cause is just. The truth is irrelevant.

If you think at these “commandments,” you will realize that they are always present on both sides, and maintained steadfastly.

Even when it is obvious from known facts that they are not the case.

1 – We do not want war.
2 – The opposite party alone is guilty of war.
3 – The enemy is the face of the devil.
4 – We defend a noble cause, not our own interest.
5 – The enemy systematically commits cruelties; our mishaps are involuntary.
6 – The enemy uses forbidden weapons.
7 – We suffer small losses, those of the enemy are enormous.
8 – Artists and intellectuals back our cause.
9 – Our cause is sacred.
10 – All who doubt our propaganda, are traitors.
