The recently assassinated Shinzo Abe once said that "whereas my physical DNA is from my paternal side, my political DNA is from my maternal side".........
It is exposed in this commentary from a renowned Hong Kong KOL that his maternal grandfather Nobusuke Kishi, Prime Minister of Japan from 1957-60 was in fact one of the chief instigators of not only the invasion of NE China in the 1930s, but also member of the think tank that later installed the puppet state Manchukuo in China, initiated huge plantations of poppies (80,000 acres) to produce and sell opium in China, and ultimately set up the infamous 731 troops as well as the poisonous gas laboratory to experiment on humans (ordinary Chinese people).
A close comrade of the WWII A+ war criminal Tojo Hideki who took responsibility for some of the most brutal war crimes in China and SE Asia, Kishe somehow escaped similar prosecutions and instead became a powerful right-wing figure of major influence in Japanese politics - well known for being a staunch supporter of the West in general and US in particular.
