Japan paid them a lot of money as compensation for what they suffered through. South Korea pocketed the money and gave the women a shitty statue. If they want to continue their grievances, they should focus on their own regime.
Which is a rather strange ideal to have. War is usually about making the other guy die gloriously for their country before taking their land, stuff, and women.
I have seen it in Germany, and I envy the Japanese Government for their stance of "We already apologized, you demanded more, so fuck all of you! We will glorify our past when not talking about it!"
