Patrick Gathara, the Kenyan cartoonist who has made a specialty of reporting about US and European events in the very same language the "western" media is reporting about "third world countries", agrees with you:

A very American riot - P.Gathara

The expressions of shock in media reports and international reactions say less about the US than about those expressing them. This, after all, is not the first time white mobs have invaded public buildings and sought to intimidate public officials in the US. In April, an armed mob invaded the state capitol building in the state of Michigan and there were armed groups of protesters targeting election officials after the November 3 vote. This is exactly what America, or at least a part of it, is.

The Trump era may be a norm-busting extreme but it remains resolutely and fundamentally American, going down the road that the US has been on for a long time. The widespread failure to acknowledge this reflects just how successful the country's propaganda efforts have been at perpetuating the myth of "the shining city on the hill" ordained by history to guide the rest of the world.
