For years, it has been fashionable to describe Cambodia as stuck: locked in authoritarian stasis, impervious to pressure, immune to meaningful change. That assessment is beginning to look suspect.

While clearly still the dominant force in Cambodian politics, Hun Sen’s legitimacy within his Cambodian People’s Party (CPP) is likely more diminished today than at any point in the past decade. And yet, just as a potential “window of opportunity” for change opens, the international response remains miscalibrated, timid and dangerously out of step with reality.

This “window” is not a moment of democratic awakening. Cambodia is not suddenly on the brink of popular revolt. In fact, pro-CPP nationalism is at an all-time high as Thai F-16s roar overhead. But popular opinion ceased to move the regime long ago, if it ever did. No, this is something far more familiar and far more consequential in a fully criminalized one-party state: a moment of incipient intraelite fracture.
