Americans demand surrender—otherwise, they tell the Japanese, "they may expect a rain of ruin from the air." The Japanese do not respond. What does Russia do? I hate history! :D

The Russians did not react to the warning of the US.

Explanation:

The United States wanted the Soviet Union to know that America had this capability. During world war I, the two emerging powers were the United States of America and the Soviet Union.

United States wanted to show the Soviet Union its power and capability of how it can be a powerful nation and threatened to destroy Japan by striking with more power and weapons from the sky, land and sea and would destroy Japan in such a way that humanity has not seen such destruction earlier.

So the US warned them that if Japan did not accept the terms of America it would drop atomic bomb on it and would destroy and killed Japanese people.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
