Soviet Motives for Gareth’s Murder?
1.Japanese implication (& embarrassment) with Gareth’s 1935 murder by Mueller’s articles effectively resulted in no further territorial expansion until the ‘Rape of Nanking’ in 1937, arguably the start of WWII.
•Allowing NKVD Wostwag not only to continue to covertly supply weapons to [Chinese Communist leader] Mao on his ‘Long March’, but also ease Soviet fears of  a war with Japan.
