There are probably a lot of ways to have the radicals win out, but let's consider a POD where Mao Zedong dies in '68 or '69 and Lin Biao succeeds him as the most powerful man in China. In this case, it is more than likely that there would be no meeting with Nixon, no "reform and opening up", no repudiation of the Cultural Revolution and most importantly for this WI, China would still encourage revolution elsewhere and support radical pro-China parties around the world.
A part of Lin's worldview was that the world situation in the 60s was analogous to Chinese situation during the people's war where colonial and underdeveloped nations were the "global countryside", and were contrasted with the developed nations ("global cities"). World revolution, then, was the act of beseizing the developed world through spread of armed struggle in the Third World. In a TL, where Lin Biao is around for a longer time, we can expect a lot of support for insurgencies in the Third World.
Another issue for the Maoists in OTL was doctrinal confusion due to theoretical inconsistencies and policy "zig-zags" taken by Mao. Maoism progressed from modestly declaring Mao as simply a more consistent follower of Marxism-Leninism than the Soviet leadership in 1961 to building a personality cult proclaiming Mao as a genius who invented a whole new stage of Marxism and then abruptly shying away from the said personality cult afterwards. It also went from berating the soviets for not being anti-US enough to being downright chummy with the US and reactionary pro-US regimes under the "Three Worlds Theory". To a lot of people, Maoism seemed confusing at best, or a downright betrayal of anti-imperialism at worst. This disadvantaged international Maoism in the 1970s, with many radicals abandoning Maoism to become Hoxhaists or simply returning to the Soviet fold. In TTL, Maoism is likely to follow a more straightforward path towards greater radicalism and remain fervently anti-US.
OTL Maoists would still be around, and likely be much stronger:
Abimael Guzmán (a.k.a Gonzalo) had already visited China in '65 and was a convinced Maoist before the POD -- so the Shining Path insurgency will probably still happen TTL. To what extent can a radically Maoist China support Gonzalo? What would be his chances TTL?
Similarly, the Naxalbari Incident had also already catalyzed radical leftists in India, and was even praised in People's Daily. Furthermore, one of the major splits in CPI(M-L) was along pro-Lin / anti-Lin lines during the campaign to "criticize Lin Biao". This split would not happen TTL, resulting in a more unified Naxalite movement. Neither would Lin ask the Indian radicals to support Pakistan in 1971 war as Mao historically did. A stronger Chinese-supported Naxalite movement still might not overthrow the Indian state, but will probably cause a lot of headaches for India in this TL, perhaps outranking the Kashmir issue as domestic problem number one. What would be knock-on effects of this?
I don't know what will happen to the NPA in the Philippines. Wiki says it was formed around 1969, it might still form TTL. What are the chances of the Philippines going Maoist? TKP/ML might still form in Turkey, but there is not a whole lot of ways in which they can get material support from the Chinese. As for Nepal, the Chinese supported the Nepali king as a Sihanouk-type figure during the cold war, but progressive radicalization of Chinese foreign policy might change this. A Nepali Maoist movement-- if it still forms in TTL-- might be able to pull off a victory with Chinese Support.
Where else can Maoist insurgencies take hold? Can we have Che committing to Maoism and not dying in Bolivia? What happens to Maoist and pro-China communist parties in the First World? If Maoist China survives past 1989, would Maoism become the most "mainstream" communism as the USSR falters?
In short, what would the most plausible Mao-wank scenario? Any thoughts?
