The text reads (according to Google translate)

I need to find out if this is true, and if so, what measures were taken.

The forced prostitution of comfort women that we take issue with is no different from the Holocaust or wartime killings.

So he’s linking it to comfort women, Korean forced prostitutes to the Japanese army during WWII. Makes sense that Korea is taking issue with shit like this, they know how bad occupying forces can get.

People don’t often think of Korea as a colony, but Japan was doing the same settler colonial shit to them the Europeans were doing everywehre else, and continue to do in Israel.
