Buchanan's book is excellent! And unfortunately Steve's commentary reflects the perversion of applying so totally different standards to Hitler in comparison with Stalin. I think Lenin himself considered this useful idiocy. And it proves how effective bolshevik propaganda really was. Hey, I have no problem if the fellow subscribing to ideas like Steve's is a card carrying leftist and/or green (just look how many die hard Stalinists of the 1970s are now staunch green) believing in dictatorship of the proletariat, but if a person proclaiming to be a staunch supporter of individual freedom (Finnish premier and staunch Anglophile Edwin Linkomies stated that Bolshevism is like a plague that must be resisted with every cell of one's body) does the same it basically invalidates that person from the ranks of rational thinkers.
As for the "Britain had to find a way into WW1" simply proves the failure of the British foreign policy in its failure to realize that the true threat to the British Empire came from North America, not continental Europe.
BTW, an excellent book relating to this topic is Russell Grenfell's "Unconditional Hatred". Also Niall Ferguson's "Pity of War" reaches the conclusion that it would have been better for Britain (and Europe) to keep out of WW1.
