For those interested in debates around the spread of Indo-European languages, I do short thred on this, with some excerpts from Robert Drews' recent (2017) book. The book is itself a revision of the claims he made earlier, principally in The Coming of the Greeks (1988).
By the way, Camille Paglia singled out Drews' 1988 book as exemplary of calm scholarship based on fact and reason as opposed to the highly ideological politicized trend in academia at the time based on trendy French theory and Marxist or post-Marxist striver moralism.
Work on later
