The tankies were correct.

In 1996, journalist Michael Smith published a book where MI6 officers, a branch of British intelligence, admitted they trained and armed Király’s fighters.8 The officer told Smith:

"We were taking them [fighters] into the mountains and giving them a crash course. I would be told to pick somebody up from a street corner at night in the pouring rain. Graz was our staging point. Then, after we'd trained them — explosives, weapons training — I took them back. We were training the agents for the uprising."

Nagy admitted such factions were active during his October 28th radio speech.

“The Government condemns the viewpoints according to which the present formidable movement is a counterrevolution [against socialism]. Without doubt, as always happens at times of great popular movements, this movement too was used by criminal elements to compromise it and commit common criminal acts. It is also a fact that reactionary and counterrevolutionary elements had penetrated into the movement with the aim of overthrowing the popular democratic regime.”

Here’s the newly released, un-redacted version. It reads:

The Hungarian Freedom Fighters were Agency sponsored.

The “Agency” in question was, of course, the Central Intelligence Agency. In the context of the JFK assassination, the CIA was suggesting anti-Castro groups meet with Béla Király, likely to replicate the Hungarian uprising in Cuba to oust the communist government.

Undoubtedly, some will downplay this revelation and claim the CIA’s role in the Hungarian Rebellion was minor, insisting it was always a popular movement against Soviet-style communism. As has been since 1956, I’ll be called a tankie for suggesting the American foreign policy establishment was 100% honest and weren’t the pristine Good Guys of History. Oh well. It won’t be the first time and it won’t be the last.

In my opinion, there is more than enough circumstantial evidence to conclude beyond a reasonable doubt that the Central Intelligence Agency encouraged, if not instigated, the bloody fighting that swept through Budapest in 1956. I don’t doubt the students and protestors shared Nikita Kruschev’s desire for de-Stalinization. But as that movement went from a demand to readjust the Hungary-Soviet relationship to outright destruction of the Soviet Union’s defensive pact in less than two weeks, there was obviously a secondary, driving force that compelled Nagy to go further. As these documents admit, Béla Király and the broader combative force were supported, trained , and armed by the CIA and MI6; you don’t need to be a genius to figure out who was pushing the Hungarian Uprising to move from civil protest to alignment with Washington D.C.’s geopolitical goals.
