keyword being “allegations”

So, the abduction of Gedhun Choekyi Nyima is more than a mere allegation. Of course, the entire selection process for the Panchen and Dalai Lamas is itself rife with controversy, as it functionally involves randomly selecting some local child and whisking them away from their parents to be indoctrinated by Tibetian monks.

Similarly, there's the open question of Taiwan's sovereignty, as well as a history of Chinese intervention in neighboring territories. Nothing compared to the US decapitation and conquest of Iraq or Afghanistan, of course. But China was absolutely involved in armed conflict with the Vietnamese back in the 1960s/70s.

You can eek out parallels and hand wave comparisons if you know the history well enough and where to look. Chinese private security firms are all over Africa, for instance. Plenty of comparisons you can make between that and the old US/Europe model of filibustering, if you squint and don't think too hard.

TL;DR; its far more than just allegations. The real difference is in scope. US interventions are orders of magnitude larger.

We've been beyond that since founding fathers.
