Chile and Argentina definitely don't make the cut.
Re Nationalist China, mass-scale civil war was entirely their baby, mostly against the Anhui- and Zhili-aligned provinces whose leadership had dominated Beiyang China. The Communists were an insignificant threat in the 20s when KMT did much of their killings, and the Communists were a "threat" that Chiang repeatedly intervened with his military to preserve - as an alibi for his plans of expropriation, systemisation, centralisation and war.
Re Japan, their rhetoric was all about uniting Asians against the colonialists. Claiming these "brothers" as subjects and ruling them. And then they stole their food, raped their women, and tested Typhus in their municipal water.
