I wonder if anyone else saw "The Pity of War" BBC2.
In it, Nial Ferguson put forward his ideas, and then debated them with a very impressive panel of historians.

Re the British Army, he is very clear that it prevented an early German victory, and that in the end it was the British Army that won the war.

His idiosyncratic theory is that a German victory would not have been a disaster.
One after the other the panel rubbished his view that there was anything benign in what they intended for Europe and the world.

It is still available on iPlayer.
Is anyone else interested enough?
