For Hitler, the 1939 Pact with the USSR was nothing more than what the 1918 Brest-Litovsk Treaty with Germany had been for Lenin: a distasteful necessity, which, with luck, would not endure very long. Lenin’s luck had been delivered by imperial Germany’s idiotic precipitation of American entry into the First World War; Hitler’s came from his own audacity and the mistakes of his slow-to-react, divided foreign adversaries. The alliance system had not caused the First World War, but the absence of alliances helped cause the Second. A debate continues over the possibility of a genuine Western-Soviet military alliance to deter and, if necessary, defeat Germany in the 1930s, including the logistical difficulties for any combined military action posed by recalcitrant Poland and Romania. But logistics can always be managed when the will is there. Sir Stafford Cripps, the maladroit, well-intentioned British ambassador, grasped that German-Soviet relations were precarious, but he could bring neither his own government nor the Soviet Union anywhere near a British-Soviet rapprochement. Given the profundity of mutual distrust between London and Moscow, only an unequivocal perception by both of the urgency of state survival could have made a bilateral alliance possible, and even then, only for a time. Of course, survival was precisely what was at stake.
Hitler’s racial, Social Darwinist, zero-sum understanding of geopolitics meant that both the USSR and Great Britain would have to be annihilated in order for Germany to realize its master race destiny. To be sure, in the immediate term, he thought in terms of domination of the European continent (
A commitment to a prolonged contest for supremacy with Britain, which Hitler expected to be aided more and more by the vast resources of the United States, made quick annihilation of the Soviet Union an absolutely necessary prelude.93 Moreover, even though Hitler and the German high command knew the Soviet Union was not poised to attack, the invasion amounted to a preventive war all the same in his logic, for the Soviet Union was only getting stronger, and might itself attack at a time it deemed more advantageous. And so, while pushing Japan to attack British positions in East Asia, he had offered the British government a version of the pact he had concluded with Stalin, in order to violate the latter, and he seemed dumbfounded that the British government did not accept.94 The Nazi leader had grasped his foe’s imperial mind-set, and he was sincere when promising that, in exchange for a free hand on the continent, he would keep Britain’s empire intact for now (its destruction, in any case, would redound to others besides Germany in the short term). He continued to hold out hope that Britain, patently weak militarily on land and therefore unable to defeat him, would see “reason.” But Hitler had failed to grasp Britain’s long-standing preference for a balance of power on the continent.95 He did, however, perceive far more common interest between London and Moscow than either of them saw themselves.
