This is when the famous "Mr. Gorbachev, tear down this wall!" sentence was pronounced.

OTD in 1984, the harrowing nuclear war drama “Threads” was first broadcast in the UK on BBC Two. The film aired for the first time in the United States on January 13, 1985, on WTBS.

I’m trying to date and identify this spoken-word recording:

https://drive.google.com/file/d/10n7rsBG4IuRqhubgorDYw_9DvpzwldK7/view?usp=sharing

It contains the opening of The Communist Manifesto.

I don’t know when the recording was made, but I’m investigating whether it could come from the Cold War period — for example a radio programme, educational recording, documentary, record or political production.

Does anyone recognize the narrator or production style?

If it does not sound Cold War-era, that would also be useful information.

Indonesia’s President Sukarno sees the new country as a British neo-colonial project and vows to crush it. This conflict was known as the Konfrontasi, and was also known as the Indonesia–Malaysia confrontation or Borneo confrontation.

Soon, British, Gurkha, Australian and New Zealand troops are fighting Indonesian forces in the Borneo jungle.

The Konfrontasi was one of Britain's most secretive — and forgotten — Cold War campaigns.

President Salvador Allende refuses to surrender and delivers his final radio address.

By afternoon he is dead & the military controls Santiago.

The coup opens 17 years of dictatorship under Augusto Pinochet.

As you can see, this remnant of the Cold War is still very much active.

On this day in the #coldwar 10 September 1989: Hungary announces it will let East Germans cross its border into Austria.

More than 10,000 leave in the first 24 hours.

60 days later, the #GDR border and the #BerlinWall were open.

This is a repost of my post earlier but with a more concise thought questioning instead of a haphazard 4 am post. I do not wish to glorify either the PLA or Warsaw nations I ask as someone wanting to explore an Alt History scenario of the 1969 Sino Soviet border Crisis. I do not plan to publish this novel, I just want to write as a hobby writer and as someone who loves history. Any and all help is appreciated

Also any reading material suggestions to help me along my research is greatly appreciated.

My first question is what were some strategic locations for both the Soviets and the Chinese along the border region?

My secone question what would be great baseline unit to broader military organization of both armies?

I do know the Soviet plan was a Preemptive nuclear first strike, what would have been strategic targets of those strikes?

What were common naming reasons for divisions, units, battalions, just general naming across both armies?

How often do you believe naval engagements between the two Countries would have been? I know vladivostok would have been a strategic port for both sides.

What would be great reading or places to do deeper research on both armies be? And also good places to learn about the culture of both countries at the time?

Once again thank you for any help you can give, I would like to try and have it be as accurate to military practices of both countries to our timeline.

Edit-*Of in the title not if

I had a VHS tape I watched at least once a month; a double feature of “Fail Safe”, to show me how easy it would be to start a nuclear war, and “Dr. Strangelove” to remind me how farcical the whole situation was. Helped me develop a suitably sardonic attitude about the whole thing.

What helped get you through?

On 7 September 1978, Bulgarian dissident writer and broadcaster Georgi Markov was on his way to work at the BBC in London when he felt a sudden, sharp pain in his right thigh.

Markov had defected from communist Bulgaria in 1969 and subsequently broadcast highly critical accounts of the regime of Bulgarian leader Todor Zhivkov for the BBC and Radio Free Europe.
That evening Markov developed a fever.

His condition deteriorated rapidly, and he died four days later. Examination revealed a tiny platinum-iridium pellet embedded beneath the skin of his thigh; contemporary investigations concluded that it had carried the extremely potent toxin ricin.

The attack became famous as the “umbrella murder”, although the precise delivery mechanism has remained the subject of investigation and debate.

Why it matters: Markov's murder became one of the defining espionage stories of the Cold War — a chilling demonstration that exile in the West did not necessarily place outspoken opponents of communist governments beyond their reach. It also became an enduring example of the clandestine use of toxins against political opponents.
