I think so. What it comes to is that insurgencies do not win militarily, but politically, since insurgents if they know what they're doing will never go toe-to-toe with a regime's army. A regime can throw everything they have at an insurgency, but if the insurgents play their cards right, the regime just sinks deeper like in quicksand.
A lot of left-wing guerrilla groups in the 1970s in Europe, the U.S., South America, Japan, etc. also got wrapped up in the cult of Che Guevara and the Foco theory. The Foco theory broke with Marxism-Leninism by believing that the objective conditions of a revolution (political support among the masses) could be generated by small bands of committed guerrillas – which was also a break from Maoist people's war!
It worked in Cuba but it failed everywhere else Che tried it, ultimately resulting in Che's death. I don't know what conclusions to draw from that. I think the Maoist doctrine has a better track record. (Adapted for Vietnam, Northern Ireland, etc.)
