Just thought this document might be of interest to readers of Machen.

He certainly was in the minority of authors represented in this 1937 booklet.

It would be interesting to know if Machen's opinion had changed by the end of his life, given that some historians find in Franco's success in the Spanish Civil War the seed that convinced Hitler that his ambitions to expand Germany's territory by military means were achievable and likely to be weakly opposed by other European powers. Machen lived to see the end of the Second World War, so the relationship between events might have occurred to him late in life.

Yes, Oldjoe, it would be interesting to know about such things. The little booklet is interesting as a document from its times. It's even interesting in terms of who was not asked for an opinion (or didn't volunteer one).
