Answer:
It was used to encourage support for Hitler by promoting racism.
Explanation:
The cartoon is a piece of Nazi propaganda that promotes racism and antisemitism.
The cartoon offers the caricature version of the Jewish person who is portrayed in a racist manner as a fat person with a big nose. We can see that she is Jewish because of David's star on the hat. A Jewish person is putting a knife into the soldier who is probably portrayed defending Germany.
Therefore, this piece of propaganda is meant to say that Jews are trying to back-stab the army, and therefore is a racist cartoon supporting Hitler.
