Agreed, also the assertion that most are Latin derived seems questionable. I count Portugal, Spain France Belgium (part), Italy, Romania, Luxembourg (French partial) Switzerland (part & not EU) . Ireland (part & saying English is Latin derived is really stretching it)
Non Latin (Germanic / Slavic) is Belgium, Lux (Lux lang), Netherlands, Denmark, Sweden, Norway (not EU) Finland, Estonia, Latvia Lithuania, Poland, Czechia, Slovakia, Slovenia, Hungary, Austria, Switzerland (part), Croatia, Montenegro, N.Macedonia, Greece, Malta, Cyprus, Ireland (part)
Did I forget anyone ?
That gives 9 Latin derived, 24 not Latin (noting double count of partial and including 2 large technically non EU)
Left out the 3 non EU micro nations of Andorra, Monaco & Lichtenstein but even if included it's 1/3 latin, 2/3rds non Latin by count. Probably the same by population but I can't be arsed to look it up
(Also ignored the UK for obvious reasons)
How was Errol Musk aware of the book (in 1970 something) if it was unpublished until 2006 ? (According to the wiki link below) ?
Were they doing nazi catch ups with Von Braun in the 60s or something ?
