Well, partly. As Graeber suggests, there may have been a distinctly European mode of imperialism which dates back to Rome - possibly earlier - and which has a consistently violent, self-justificatory, and abusive character.

Unlike Graeber I'm still not convinced this is a particularly European approach to war and conquest. But Europe certainly evangelised it more effectively than any other culture, both physically with a greater geographic spread and intellectually with an impressive cultural carpet bombing.

The same mode is still active today, although it has been somewhat demilitarised except at the edges of the empire, and significantly abstracted into political and financial violence.

It's still evangelically potent, however. In fact it's pretty much the official state religion of the West, in the moral sense of ordering everyone's goals, values, and activities.

In comparison, the 'official' religions are just entertainment.
