To get back to my comment where I explained what I consider to be a reasonable interpretation of "national character," I defined it thus:
[N]orms that the British government is known to follow consistently in practice, and expected to follow by a broad consensus of the British people -- such consensus being strong enough that it can be considered part of their national character.
In this discussion, I am not at all interested in the exact connection that these norms have with ethnicity or any other factors. I merely claim that for whatever reason, there is variation in such norms across governments, which sometimes gives very strong information on what they may be capable of doing.
(And anyway, several decades of life under radically different regimes imposed by foreign conquerors, one of which practices extreme isolation, will cause cultural divergences that run deeper than the immediate structure of clear incentives. Moreover, this one example is not conclusive proof that all such differences in governments' behaviors in all places and times are caused by the same factor.)
But I think that such a definition where "national character" are the norms followed by a a national government and which it's expected to be followed by a broad consensus, leads to bizarre ideas such as e.g. the "national character" of the whole of Eastern Europe must be described as having changed at the fall of communism, even though the fall came from within. So the national character suddenly modified itself, just because the norms of government changed themselves. Eh. I don't think that's really how these words are normally used.
