Yes.
because they were black
Singapore did not play a part in the Bombing of Darwin, which was carried out by Japan against Australia in 1942. Singapore's connection would be that the country fell to Japan just days before the bombing.
The bombing of Darwin pulled Australia into the war against Japan. Australia was totally unprepared for this attack. This bushed the country into a wartime economy which is actually advantageous for growth.
Bombing or invading Japan
Australia entered the war with Japan in 1941 because of the bombing by Japanese planes that occurred in the Hawaiian Islands. After the Japanese were done with the Americans, they turned their submarine and air force warfare towards Australia.
atomic bombing
To get more people to fight on there side so that they can win. Japan is psycologically impared and they dont have squat for space in there country. Probably the same reason James Cook and the English did, they wanted land...
Australia saved itself. Australia had seven army divisions defending the country. Japan could not moster even a full division when it moved down the Kokoda Track.
The first bombing of Japan in World War 2 was the Dolittle Raid.
Yes they hated the Japanese enough to the point that they celebrated the bombing of Japan.
Japan never intended on, in a sense, "winning" against Australia in the bombing of Darwin. Japan's Imperial Forces wanted the rich oil and natural gas resources in Indonesia and PNG (Papua New Guinea). Because they did not want Australian or American forces interfering with their plan to harvest the rich natural resources of these two countries, Japan decided to put fear into Australia by bombing one of its ports. Australia had prepared for a very long time for future bombings in all major cities, including putting 10km tunnels from schools to bunkers under the city of Melbourne. So Australia had prepared for bombings on a huge scale from Japan, luckily they never occurred in truly important cities, Australia had also prepared for a Nuclear War from the Soviet Union
It was the measure to make Japan surrender in ww2.
