This propaganda is targeting young American men by depicting Germans as brutes who deserved to be killed. The tone is appropriate to the society because the Germans did not have a great reputation thus far in WWI. The poster shows a woman representing Liberty in the clutches of a German ape, which would show that freedom needs protection from Germany. The slogan "Destroy this brute!" is quite catchy, and it would probably stay in the audience's mind. One can imagine that young men would feel compelled to join the army after seeing this poster, but not manipulated into joining by this poster. The poster would have made young men join of their own decision, to stop the Germans from taking people's freedom away.
