We don't need the nazis to destroy us. we are destroying ourselves, what does he mean by this

This is from the Diary of Anne Frank. Mr. Frank is the one who says this line. The Jews in hiding have been fighting over food. Because of the German forces raiding farms and taking most of the food for the soldiers, there is very little food to around. It's even harder for those in hiding to get food. Mr. Frank sees the fighting over the food as a way the Jews are destroying themselves. They cannot be divisive if they want to survive. If they are at war with each other inside of their hideaway, they'll eventually destroy themselves, the Nazis won't get the chance.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
