This is news to you? The US started what became the Cold War. Russia was faced with a belligerent, superbly armed and overtly hostile superpower that had military control over its seaports, trade routes, raw materials sources, and important borders. And Russia was just about exhausted. It had just fought the most destructive winning war in history. It had lost 20 million people - the best and the brightest of a generation, in fact the core of the generation itself. Its infrastructure was destroyed, its cities without food and water let alone heat and power, its roads and agriculture run over by the massed armor of the Third Reich. And on its borders were the armed forces of a country whose army had already launched a trial invasion, whose military production was just hitting its stride, whose army was large, well-rested by comparison, well-equipped, and poised to strike; whose leaders were whipping up hysteria about the threat it posed and the necessity of armed "resistance". When your enemy is in a mad race to arm itself against you, exaggerating your threat and provoking dangerous situations (even armed conflicts) on your borders, would you be wise to prepare for an attack? Would you seek allies and border buffers, attempt to undercut your enemiy's power, deflect your enemy's efforts elsewhere? And the ICBM made everything easier. The US settled down to proxy wars across the globe, Russia countered likewise (in humbler style, with less corruption, more idealism) and the age of the AK47 began.
