Historiography has traditionally laid most blame for the annexation crisis at the Austrian Aehrenthal's door. The historian [[Chris Clark (historian)|Christopher Clark]] however, in his 2012 study of the causes of the [[First World War]] ''The Sleepwalkers'', has challenged this view "the evidence suggests that the crisis took the course it did because Izvolsky lied in the most extravagant fashion in order to save his job and reputation. The Russian foreign minister had made two serious errors of judgement [firstly] that London would support his demand for the opening of the Turkish Straits to Russian warships - [and] he grossly underestimated the impact of the annexation on Russian nationalist opinion - [when] - he got wind of the press response in St Petersburg, he realized his error, panicked, and began to construct himself as Aehrenthal's dupe." <ref>Clark, The Sleepwalkers, p.86</ref> The years following the annexation crisis, in an atmosphere of increased 'chauvinist popular emotion', and with a sense of humiliation in a sphere of vital interest, saw the Russians launch a substantial programme of military investment.<ref>Clark, The Sleepwalkers, p.87; David Stevenson, Armaments and the Coming of War, Oxford 1996, pp. 162-63</ref>
