Many peaceniks from the Left blame the US for everything. Now they even don't get the idea that the US has every right to disarm Iran, North Korea, and many other countries. One of their favorite argument is:
"The US is a hypocrite since they already nuked Hiroshima and Nagasaki, therefore they don't have the right to prohibit others from acquiring nukes!"
That means they never read history. Or choose to ignore it. Here, let me enlighten you guys:
The Terror of Imperial Japan
Hey, peaceniks, if you think USA is nasty and hypocritical, just try dealing with the Imperial Japanese of the 1930s & 1940s! They raped and massacred the whole city of Nanking, and created a systematic sexual slavery across their vast territories! Yes, let me stress it again: SYSTEMATIC SEXUAL SLAVERY! Got that? Oh, they also spouted that we have to support their empire, since they were creating "The Great Asian Co-Prosperity Sphere." Yeah, they had the nerve to declare sexual slavery as "prosperity"!
None of us buy that b.s. We in Indonesia have a saying "350 years under the Dutch is nothing compared to 3.5 years under the Japanese." Heck, my own grandpa told me the stories how the Japanese stole EVERYTHING from his house, even every single nails and bolts.
And don't let me start about their war mentality. They are baffled by the idea that any surrendered enemy combatants has to be treated with respect. Hey, who can blame them? In their honor-based culture, "surrender" is the apex of disgrace. That's why they keep fighting and fighting, AND RAPING in between. That continued even after the Allied started sending waves and waves of B-29 bombers in mid 1944. The destruction of their fleet, and the end of their oil supply from Southeast Asia in October 1944 didn't convince them to surrender either. Any sane government would throw the towel after that, but nope. To hell with sanity and the well-being of their people, the Imperial Japan keep fightin since their priority is THEIR HONOR!
USA vs Others?
Hey, with that mentality, how can you protest when the US finally nuked their cities? They had it coming. Others wouldn't be that nice. Let's say the Japanese faced nuclear-equipped Russians instead of Americans at that time. The Russians are never as squeamish as the Americans. To ensure the maximum effect of the atomic bombs, they would start nuking Tokyo and Kyoto, the political and cultural capital of Japan. If they have more bombs, they would nuke Osaka, Kobe, and other major cities too.
And now you peaceniks think that Americans is immoral? What other options they have? Here, let me show the other options to you:
A) Stop the war by agreeing "peace" with the Japanese, accepting their terms.
The Japanese were eager to keep China and many other "Asian Co-Prosperity Sphere." Good luck telling that with a straight face to the Chinese. They would be enraged! They would continue their war against Japan. People in other area like Indonesia would either die in millions because of the harsh treatments, or die in millions because they finally rebel, but the Japanese use superior firepower to massacre them.
B) Asking the Japanese to surrender unconditionally and immediately, renouncing all of their conquest.
Do you live in a fantasy world where "HONOR" were never a part of Japanese culture? Like I said before, they would do EVERYTHING to avoid losing face, even keepin a losin war goes on and on. What's next, asking lions to be vegans?
C) Just keep bombin and blockadin Japan until they surrender
The famine in Japan would be amplified. There would be outbreak of nasty diseases. Japanese would die in millions, slowly, excruciatingly.
Oh, same thing would happen in their colonies too. That means, another millions would die in China, Indonesia, Indochina, etc.
Oh, the Russian actually planned to invade Manchuria, Korea, and Northern Japan. That means not only Manchuria and North Korea, would fall into communist hand. South Korea and Hokkaido would be grabbed by the communist. Say hello to the "People's Democratic Republic of North Japan." Say hello to total domination of Korea Peninsula by Kim Il Sung's dynasty.
D) Direct invasion to Japanese Homeland
US Navy and Army planned this invasion because they were unaware of the atomic bombs until last minute. They knew the invasion would be ... nightmarish at best. Not only thousands of Allied's and Japanese sailors and soldiers would die, millions of Japanese civilian would perish too. Hey, they already taught their CHILDREN to use a sharp bamboo spear to disembowel Allied soldiers! Those who can't fight would choose suicide instead of surrendering to the Allies. We know that because that was what happened in Saipan and Okinawa. The civilian population plunged to a cliff WITH THEIR BABIES in their hands, instead of surrendering. I can say 5 millions civilians dead already sounds optimistic.
Oh, since the Allies busy with the invasion, nobody would dare to question the Russians when they rolled to South Korea and Hokkaido.
As you can see, the other options are FAR WORSE than the atomic bombing of Hiroshima-Nagasaki. It was THE BEST CHOICE among several nightmarish options. The root of the nightmare is the honor-based Japanese culture. Even the peace party in Japan couldn't convince everyone else. They need Hiroshima-Nagasaki, AND Soviet invasion to silence the war party. Blamed Tojo, Hirohito, and other Japanese militarists, not Truman or the US.
Don't like that? C'est la vie, life is not consisting of easy black-white option. Grow up and stop whining about your never-exist childish dream. Hard choices have to be made, and we will be damned if we close our eyes and fool ourselves that all choices are easy.
