It's new to me that People Republic of Korea is exporting large amounts of drugs
I kind of thought was that Columbia, Afghanistan and Golden Triangel were the biggest Drugs export nations...
But it's intriguing Idea 1960s China as world larges Opium and Heroin producer, that dump there products on Capitalist market.
in same time win financially and Propaganda "Look how decadent are Capitalist youth"
Bonus if that Happen during Vietnam War having Pipeline from South Asia to USA by Military Cargo transport US-Frontline.
(Real life example: Gangster Frank Lucas smuggled heroin using the coffins of dead American servicemen)
A interesting speculation: Would China keep the Vietnam War ongoing to have supply Pipeline into US or will look for other way to bring there Drugs to US?
The other side: How would the USA Government react on the news China is selling Opium and Heroin to US crime syndicates ?
Declare War to China, Bombing the Chinese Opium fields with Napalm bombs ?
Little Problem here China is a Nuclear Power since 1964, they can strike back.
But there is more sinister plot the USA could exploit the ongoing Sino-Soviet conflict !
They could increase the conflict, declare the USA is neutral in conflict and watch how USSR does a nuclear Attack on China.
(Real life example: in 1968 Soviet really planned this, but the Wildcard were USA, so Soviet Diplomats ask "If we (theoretical) does a nuclear attack on China, what will US do ?" Henry Kissinger realized what going on and replied "the USA will stand at side of China and strike back")
And how would be a 1970s War on Drugs in USA under Nixon and later Ford ?
Special if Capitol Hill give them "Free hand" to deal with situation...
Wild speculation: would this let to situation Phillip K. Dick describes in his novel A Scanner Darkly ?
A USA under police invasive surveillance with narcotics agents remain anonymous, to avoid collusion and other forms of corruption...
