I agree and have also been planning to add this. I added a section on the US imperialism page that draws from this source, feel free to use any of what I wrote there if you want to: https://en.prolewiki.org/wiki/United_States_imperialism#Anti-base_and_U.S._military_withdrawal_movements
For this ROK article, I was considering adding it under "Politics" in a section about comfort women and their ongoing activism (as the article mentions that unlike comfort women who were victims of the Japanese and do receive some degree of recognition for that, the victims of this US prostitution program don't receive the same recognition). I also thought including certain time periods mentioned in this article through the history sections (e.g., mentioning some of the court cases under the relevant ROK republic eras in which they occurred), and also including other US military crimes against ROK citizens in more modern times (which I mentioned in the USA imperialism article).
I'm happy to work together on this or for one or the other of us (or anyone else) to add this information in any way they see fit, these were just the ideas I was thinking for how to organize it.
