Sure you have. You've just been caught being disingenious about it.
You claimed, for instance, that it was the mobilization that led to war.
Then you'll point to Russia's announcement of preparations, clearly implying that Russia was mobilizing.
But Russia didn't mobilize (not yet); that's an inconvenient fact in both yours and Keegan's absurd historical revisionism...a fact that is easy to expose when viewed next to the timeline for war.
