"By a stringent line-by-line analysis of the terms of Austria’s 48-hour ultimatum to Serbia and the Serbian reply, Clark demolishes the standard view that Austria was too harsh and that Serbia humbly complied. Austria demanded action against irredentist networks in Serbia. It would have been an infringement of sovereignty, yes, but Serbian tolerance of the terrorist networks, and its laid-back response to the Sarajevo murders, inhibit one’s sympathy with its position. Clark describes Austria’s ultimatum as “a great deal milder” than the ultimatum presented by NATO to Serbia-Yugoslavia in the March 1999 Rambouillet Agreement for unimpeded access to its land. As for Serbia’s reply, so long regarded as conciliatory, Clark shows that on most policy points it was a highly perfumed rejection offering Austria amazingly little — a “masterpiece of diplomatic equivocation.”

The same review notes:
"Both authors put a stake through the heart of a common narrative that has Germany mobilizing first so as to spring the preventive war its generals had long advocated. It didn’t. Clark documents how Berlin’s political and military leaders stuck to their blithe belief that any conflict could be localized. Russia’s mobilization, he says, was “one of the most momentous decisions of the July crisis. This was the first of the general mobilizations.” McMeekin says that Russia’s crime was first in escalating a local quarrel by encouraging Serbia to stand up to Austria-Hungary and then accelerating the rush to war. He faults Barbara Tuchman in her classic “Guns of August” for misdating Russia’s mobilization two days later than it was ordered. He is no apologist for Germany. In “The Berlin-Baghdad Express” (2010), he nailed the Kaiser as a half-crazy jihadist inciting Muslims against Anglo-French interests in the faltering Ottoman Empire, but his 2011 book “The Russian Origins of the First World War” lived up to its title."
