“Hitlerism exercised its strong international and inter-European appeal during the thirties because racism, although a state doctrine only in Germany, had been a powerful trend in public opinion everywhere.”

The point is that both Hitler and Stalin held out promises of stability in order to hide their intention of creating a state of permanent instability.

Courage is indispensible because in politics not life but the world is at stake.

The third world is not a reality, but an ideology.

It is quite gratifying to feel guilty if you haven’t done anything wrong: how noble! Whereas it is rather hard and certainly depressing to admit guilt and to repent.
