I highly recommend looking at Geisel’s war cartoons:

It is impossible to reconcile his Left wing views to the present Pacifism of the modern radical left.
Many of Geisel’s cartoons could be thrown on the modern editorial page as indictments of the anti Iraq war attitude.
It is one of the best examples of how the Left has fundamentally changed to the Old Right of the 1930s.
PM was a hard core pro-Stalinist publication. It supported the war effort only because Hitler threatened the Soviet Union.
