1955年,当莫斯科引爆了首枚氢弹之时,冷战的开始就确定无疑了。这是一种可以彻底摧毁大城市的理想武器,威力是原子弹的1000倍左右。氢弹的出现,结束了美国的核垄断地位并对其构成了致命的威胁,华盛顿因此不得不格外谨慎地应对莫斯科,从而开始了一个彼此担心互相毁灭的冷战时期。 When the first hydrogen bomb was detonated in Moscow in 1955, the beginning of the cold war was certain. This is an ideal weapon to destroy the big cities completely. The power is about 1000 times that of the atomic bomb. The appearance of the hydrogen bomb ended the United States’ nuclear monopoly and constituted a deadly threat to Washington. Therefore, Washington had to deal with Moscow with extra care and thus started a Cold War era that feared each other’s annihilation.
