Remarkable insight...

If people do sometimes use words like "root cause" as a way of avoiding identifying root causes, that's a pity, but it doesn't alter the fact that it's important to work at identifying these kinds of contributory factors.

Blaming human wickedness, and stopping at that isn't good enough.

Something like Nazism, for example, didn't just come out of nowhere - it had roots in all kinds of things, including the imposition of punitive reparations on Germany. In the aftermath of the Second World War, it was very fortunate that there were people around who were capable of thinking in terms of those kinds of factors, who didn't just stop at seeing Nazism merely as a matter of wickedness, and who were able to make sure that some of these same mistakes were not repeated. (And it's as well to remember that there were people around who denounced that kind of thinking as somehow betraying the victims of Nazism.)

And again, it was important that people recognised in the widespread record of anti-semitism in various countries, including those which fought against Hitler, one of the seeds of Nazism.
