No, I have never read anything from these two people. I just skimped the work of Henry Makow and wikipedia about David Irving after you mentioned them. In short, they do have some merits in their works, but I do have some objections:
- I believe in "class struggle" of Karl Max. I don't accept any attribution of "doing bad" such as imperialism to any people, but only social class. That is to say that it is the fault of financial capitalists which may have lots of Jewish people in certain country and certain time. Their ethnic background plays no role doing bad. The word Jew should not have been in the title with or without quotation marks.
- The established history view after WWII are made by the winners. The view includes some obvious whitewashing or omission of atrocities against German and Japanese civilians by US, UK and USSR. However, trying to whitewash Hitler is not acceptable. One of David's argument is the lack of evidence of order from Hitler to exterminate the Jews. David missed the point or disagree with the point that there were millions Jewish civilians killed at the hand of Nazi troops, Hitler as the highest leader together with the whole leadership are fully responsible for that, regardless written order or not. Technicality in legal code of the time does not get them away from the guilt. In this regard, winner's rule is the rule.
I skipped reading the rest about their work because I believe with these two fundamental differences the rest of what they say does not matter much to me, what can be agreed I probably already know through my own study.
Unfortunately for DAVID IRVING, to learn his works one will have to read BOOKS, and definitely no way to use the CIA's front-end filtering so-called faux online encyclopedia Wikipedia

lol -- I esp. won't touch any politically sensitive subject using wikipedia! for sports, entertainment and other fun things, okay.
but this British researcher (sorry, my bad, not American) was deadly serious on his works, he did research for three years, dug the very thick piles of the war and war trial documents... and he was good at his works that the establishment poured in efforts to destroy his life to shun his works... and it's hard to find some good info about him online, the establishment has painted black on him every where: holocaust denial, antisemitic, even history falsifier, etc.
Some of his books:
- Hitler's War and the War Path by David Irving
- Churchill's War, Vol 1: The Struggle for Power by David Irving
- Churchill's War, Vol 2: Triumph in Adversity by Irving David
- Nuremberg: The Last Battle by David Irving, Walter Frentz
- and several others
- Lying About Hitler: History, Holocaust And The David Irving Trial by Richard J. Evans
In ruling against the controversial historian David Irving in his libel suit against the American historian Deborah Lipstadt, last April 2000, the High Court in London labeled him a falsifier of history. No objective historian, declared the judge, would manipulate the documentary record in the way that Irving did. Richard J. Evans, a Cambridge historian and the chief advisor for the defense, uses this pivotal trial as a lens for exploring a range of difficult questions about the nature of the historian's enterprise.
For instance, don't all historians in the end bring a subjective agenda to bear on their reading of the evidence? Is it possible that Irving lost his case not because of his biased history BUT BECAUSE HIS AGENDA WAS UNACCEPTABLE? The central issue in the trial -- as for Evans in this book -- was not the past itself, but the way in which historians study the past.
In a series of short, sharp chapters, Richard Evans sets David Irving's methods alongside the historical record in order to illuminate the difference between responsible and irresponsible history. The result is a cogent and deeply informed study in the nature of historical interpretation.
As for HENRY MAKOW, he wrote many articles, manages his own website, thus more readily accessible, the link I gave earlier is a good starter. His subjects are completely different, not those faces, names that we regularly mention here or in the press, he's referring to the "supreme powers", extremely ultra wealthy, the generationally wealthy families (power and wealth developed long in the past, from at least the Battle of Waterloo era), the master class, the masters of all those political class in the West, the founders and controllers of many institutions, from the central banking, banking & financial, media, secret agencies, MIC, think tanks, and myriad of things... some even pointed out that they're controlling over 10,000 largest enterprises in various important sectors globally (esp. in the Western countries, but also in the "white" Asian like Japan).
