This is actually WAD. Imperial World View fits the UK, as designed; it represents the outlook that considers defence as a combined Empire, not as a parochial 'Homeland' with "owned nations". The British High Command mostly thought this way - which is a primary reason they wanted to avoid war (Britain stood to gain nothing from a war, but stood to lose an Empire - which, indeed, it did as a result of WW2).
Conciliatory is really closer to the French view that, having been bled dry by WW1, another war was unthinkable. It's true that France had a strain of Imperial World View as well, but Conciliatory represents ths political ennui and disarray of 1930's France rather better.
Imperial World View, to be clear, is a world view of a nation that already has an Empire, not of a nation that wants to build one - Frustrated Expansionist is designed for that.
