I'm not surely this really deserves a response, but....the first two at least (and the title of the third presumes) that they are histories of the military development of the war. Churchill and Eisenhower talk at length about numbers of tanks and where divisions were posted....very much a telling of the war, as opposed to the details of civilian life. Churchill, for example, does not appear to mention evacuees - should we therefore assume that they also did not exist?
Between the three, there are over 7000 pages printed. Don't you find it strange that not one of these high ranking men mention the gassing of individuals?
I've actually been here http://www.kz-gedenkstaette-dachau.de/index-e.html
I've seen the solid (litterally) concrete evidence. I've seen the piles of human hair and shoes.
The Archive at Dachau contains;
Photos (current count over 6,000)
Plans (Maps, Blueprints, Layouts)
Original 3-Dimensional relics
Phonograms (current count 350)
Films (current count 1,200)
The archive contains a variety of sources, particularly: eye witness reports of survivors, documents related to the development and management of the camp, post-war trial records, and holdings of the international prisoner committee founded after liberation
Plus the library has over 14,000 documents relating what happend there.
You can go see this stuff yourself. This is just 1 camp.
You can't say that 10's of thousands of people made up the same story. You can't say all of the 1,000's of photos are made up.
You can't say the prefabricated bunkers were made post 1945 to make the nazi regime look bad.
You can't say all of the SS troops who confessed at trial were lying.
I can tell you that I had breakfast this morning.
I can show you the cereal packet.
I can show you the used milk carton.
I can show you the dirty bowl.
I could, at a push, regurgitate some of it and fedex it to you in a bag.
You could still say that because you hadn't seen me eat it that I didn't have breakfast. You would, however, be denying something that on the balance of probabilities you could be 99% sure did happen.
Before you do it don't make the mistake of comparing something verifiable and human with something that is make believe...
