Thanks for the translation. I had no chance in obtaining it otherwise, as I
don't even have the fonts necessary to express it for the online
translation sites, let alone that the sentences are part of an image and
not text available for copy to the clipboard.

Roughly as follows, and since it takes effort to translate the
manga histronics of the slogans I probably won't do more or
comment more about anything beyond this email unless radio
related.
Top slogan: Against oppression -- a mighty blow i.e., smash US's
oppression of us with a crushing assualt or strike
Bottom: Against castigation -- ruthless beating, i.e., merciless
punishment for the way we are derided and treated.

These are Chinese character derived so although simple syllables
are saturated with varied meanings that cannot be simply
translated into another language except Chinese or Japanese..

By the way, North Koreans live and breathe these slogans. They
fervently believe them and will gladly die for them, especially
the troops and average person. .
