Answer:
The Soviet Union developed its own atomic bomb.
Explanation:
Among the world leaders, the United States was the first to develop and even test out its nuclear weapon. The attack of Hiroshima and Nagasaki during the Second World War helped project the US as the most powerful power.
But the development of nuclear arms by the Soviet Union led to competition for the world power. The Soviets developed their own atomic bomb and tested its very first atomic bomb in 1949.
