Bye war crime denier. Hello probably worse war crime denier. I like know shit about Japan's politics other than their Communist party are soc dems (wouldn't be able to exist otherwise) and the largest non ruling Communist party in East Asia, and Liberal Democrats are shit but always remain in power.
tbh no communist party in the world with parliament representation but not in power is. They are all deeply entrenched in bourgeoise politics already.
From what I understand, kinda were flawed from the start back in the 20's as they were very much like the SPD. They basically had to renounce revolution to exist. Should still be more radical tho.
