Final answer:
Reactions to the WWII nuclear attacks ranged from understanding to condemnation, affecting political strategies, public opinion, and leading to the Cold War and a redesigned Japan.
Step-by-step explanation:
The international reaction to WWII nuclear attacks was diverse, with diplomatic responses, public opinion, and political ramifications varying widely. Initial shock and condemnation were prevalent among the American public and the international community. Political leaders from various countries had to reassess their own military strategies and diplomatic relations in the face of this new, devastating technology. Some saw the bombings as a necessary evil to end the war and save lives, while others viewed them as an inexcusable act of brutality.
Political ramifications included rapid moves towards establishing the United Nations and starting the atomic age, which ushered in the Cold War. Public opinion was polarized globally, with many questioning the ethical implications of using such a weapon against civilian populations. As for diplomatic responses, while Allied governments mostly supported the decision, it sparked a race for nuclear armament, particularly with the Soviet Union which led to the start of the Cold War. The destruction also influenced the postwar reconstruction of Japan, pushing it towards demilitarization and refocusing its constitution on human rights.
