"The Sneer Strikes!" Superman Daily Newspaper Strip - June 28, 1943 to August 21, 1943
More than a few fictional characters toured the Japanese-American internment camps which dotted the west coast after 1942, the goal of their tours largely being to console the uneasy consciences of Americans troubled by the objectionable actions of their government towards literally tens of thousands of their fellow citizens. Clark and Lois visit one camp and - following a superficial tour - find it good, effectively stamping the entire controversial endeavor with Superman’s approval. A low point in Superman’s history.
Making their judgment call from the tourist perspective, Clark and Lois find the interned citizens of Japanese descent to be “decent, hard-working, honest Americans” … for the most part. Fifth column activities - unsurprisingly, given the circumstances - nonetheless pop up in the camp, necessitating Superman’s intervention.
This time, last year, in the newspaper dailies, Superman was clashing with the insidious Japanese agent The Leer, who destroyed himself rather than risk capture. Now, the Leer is back — or so it seems, as it’s actually the original agent’s lookalike brother, his face also contorted in a permanent rictus.
