Why did president harry truman decide to hit the japanese cities of hiroshima and nagasaki with two atomic bombs in 1945?

President Harry Truman wanted to put an end to the war. Germany had already surrendered, and the only open front was the Pacific Theater, where American troops were fighting hand-to-hand in Japanese territory against Japanese forces.

The truth is that during these battles, especially during the Battle of Okinawa, Japanese forces showed courage and total dedication to the cause, which led them to fight to the death, literally. There was no surrender, and the few Japanese who survived did so with really disabling wounds. Every Japanese fighter who could continue fighting did so, giving up his life for his nation and, obviously, requiring more effort and a greater cost of American lives.

This situation led the American military commanders to realize that an invasion of Japanese territory was unfeasible, since it would be a massacre, with an incalculable cost of American lives.

To avoid unnecessary lengthening of the war, and a number of pointless American deaths, President Truman made the decision to carry out an attack with a force so great that it would deter Japan from wanting to continue the war. Thus, the United States dropped the atomic bombs in Hiroshima and Nagasaki, which showed Japan the war power of the United States, forcing its surrender.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
