This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book shows that news of the 'final solution' had been received in 1942 all over Europe. The order had practical consequences, it affected the lives or, to be precise, the deaths of millions of people. For this reason details about the 'final solution' seeped out virtually as soon as the mass slaughter started. Jewish leaders and the public abroad found it exceedingly difficult in their great majority to accept the ample evidence about the 'final solution' and did so only with considerable delay. The neutral governments received much information about the 'final solution' through many channels. In London and Washington the facts about the 'final solution' were known from an early date and it reached the chiefs of intelligence, the secretaries of foreign affairs and defence.
