Pearl Harbor was attacked in December 1941, the Manhattan Project was created in 1941, the program was created to secretly built an atomic bomb, it was originally projected against Nazi Germany, but in May 1945 Germany surrendered and the US still had the bomb and still was at war with Japan that did not surrender.
They were four years into the war, the US Army invaded Okinawa and Iwo Jima, yet the Japan military resisted.
In July 1945 the Manhattan project successfully detonated the atomic bomb in a test site in the desert of New Mexico.
There was another element into question: The Soviet Union entered the war against Japan and the atomic bomb would send a strong message to the Soviets. This way, Truman decided to drop the bomb on the city of Hiroshima on August 6th of 1945, three days later another bomb was dropped over Nagasaki.
On August 15th Japan surrendered ending the WWII, and Truman faced heavy criticism. Some argued that Japan was on its knees and the bombs were unnecessary, others pointed to the Soviets as a motive.
The bomb ended WWII but started the long Cold War with the Soviet Union, it lasted 50 years and ended with the fall of the Berlin Wall.
Answer:
The cause of the firefight between Soviet and Chinese troops was a matter of dispute. The Soviets charged that Chinese soldiers crossed the border between the two nations and attacked a Soviet outpost, killing and wounding a number of Russian guards. The intruders were then driven back with heavy casualties. The Chinese report indicated that it was the Soviets who crossed the border and were repulsed. Either way, it was the first time that either side openly admitted to a clash of arms along the border, though it had been rumored for years that similar run-ins were occurring. Ever since the early-1960s, relations between the two communist superpowers had deteriorated. China charged that the Soviet leadership was deviating from the pure path of Marxism, and by the mid-1960s, Chinese leaders were openly declaring that the United States and the Soviet Union were conspiring against the Chinese Revolution.
Explanation:
basically China crossed the border to attack and killed a number of soviets, then later on accused the Soviets of crossing the border and attacking them so ever since they always basically hated eachother.
