Well, the cartoonist is actually critical of Hitler in the drawing. The cartoonist is satirizing the appeasing position that many people had with Hitler, perhaps out of fear, but most likely out of hidden sympathy that with time became more and more explicit until the point that many people came out as Nazi supporters in the end.

Explanation: On the Western Front, the war was fought by soldiers in trenches. Trenches were long, narrow ditches dug into the ground where soldiers lived. They were very muddy, uncomfortable and the toilets overflowed. These conditions caused some soldiers to develop medical problems such as trench foot.
Soldiers in the First World War did not spend the whole of the time in the trenches. The British Army worked on a 16 day timetable. Each soldier usually spent eight days in the front line and four days in the reserve trench. Another four days were spent in a rest camp that was built a few miles away from the fighting.
As part of the Omaha Platform, the People's Party demanded that there be a reduction in the working day fair, a safe, sound and flexible national currency, assistance to farmers with the financing of their labors, fair and liberal pensions to ex-Union soldiers and sailors, the direct election of the Senators, single terms for Vice-Presidents and Presidents, initiatives and referendums to be readily available, a secret ballot system, the nationalization of railroads, telegraph, postal systems and telephone systems a graduated income tax and the free and unlimited coinage of silver.
