A few small anarchist and pacifist groups refused to back the war. The Women's International League for Peace and Freedom said: "… war between nations or classes or races cannot permanently settle conflicts or heal the wounds that brought them into being." The Catholic Worker wrote: "We are still pacifists…"

The difficulty of merely calling for «peace» in a world of capitalism, Fascism, Communism- dynamic ideologies, aggressive actions-troubled some pacifists. They began to speak of "revolutionary nonviolence." A. J. Muste of the Fellowship of Reconciliation said in later years: "I was not impressed with the sentimental, easygoing pacifism of the earlier part of the century. People then felt that if they sat and talked pleasantly of peace and love, they would solve the problems of the world." The world was in the midst of a revolution, Muste realized, and those against violence must take revolutionary action, but without violence. A movement of revolutionary pacifism would have to "make effective contacts with oppressed and minority groups such as Negroes, share-croppers, industrial workers."

Only one organized socialist group opposed the war unequivocally. This was the Socialist Workers Party. The Espionage Act of 1917, still on the books, applied to wartime statements. But in 1940, with the United States not yet at war, Congress passed the Smith Act. This took Espionage Act prohibitions against talk or writing that would lead to refusal of duty in the armed forces and applied them to peacetime. The Smith Act also made it a crime to advocate the overthrow of the government by force and violence, or to join any group that advocated this, or to publish anything with such ideas. In Minneapolis in 1943, eighteen members of the Socialist Workers party were convicted for belonging to a party whose ideas, expressed in its Declaration of Principles, and in the Communist Manifesto, were said to violate the Smith Act. They were sentenced to prison terms, and the Supreme Court refused to review their case.

A few voices continued to insist that the real war was inside each nation: Dwight Macdonald's wartime magazine Politics presented, in early 1945, an article by the French worker-philosopher Simone Weil:

Whether the mask is labeled Fascism, Democracy, or Dictatorship of the Proletariat, our great adversary remains the Apparatus-the bureaucracy, the police, the military. Not the one facing us across the frontier or the battle lines, which is not so much our enemy as our brothers' enemy, but the one that calls itself our protector and makes us its slaves. No matter what the circumstances, the worst betrayal will always be to subordinate ourselves to this Apparatus, and to trample underfoot, in Its service, all human values in ourselves and in others.

Still, the vast bulk of the American population was mobilized, in the army, and in civilian life, to fight the war, and the atmosphere of war enveloped more and more Americans. Public opinion polls show large majorities of soldiers favoring the draft for the postwar period. Hatred against the enemy, against the Japanese particularly, became widespread. Racism was clearly at work. Time magazine, reporting the battle of Iwo Jima, said: "The ordinary unreasoning Jap is ignorant. Perhaps he is human. Nothing… indicates it."

So, there was a mass base of support for what became the heaviest bombardment of civilians ever undertaken in any war: the aerial attacks on German and Japanese cities. One might argue that this popular support made it a "people's war." But if "people's war" means a war of people against attack, a defensive war-if it means a war fought for humane reasons instead of for the privileges of an elite, a war against the few, not the many-then the tactics of all-out aerial assault against the populations of Germany and Japan destroy that notion.

Italy had bombed cities in the Ethiopian war; Italy and Germany had bombed civilians in the Spanish Civil War; at the start of World War II German planes dropped bombs on Rotterdam in Holland, Coventry in England, and elsewhere. Roosevelt had described these as "inhuman barbarism that has profoundly shocked the conscience of humanity."

These German bombings were very small compared with the British and American bombings of German cities. In January 1943 the Allies met at Casablanca and agreed on large-scale air attacks to achieve "the destruction and dislocation of the German military, industrial and economic system and the undermining of the morale of the German people to the point where their capacity for armed resistance is fatally weakened." And so, the saturation bombing of German cities began-with thousand — plane raids on Cologne, Essen, Frankfurt, Hamburg. The English flew at night with no pretense of aiming at «military» targets; the Americans flew in the daytime and pretended precision, but bombing from high altitudes made that impossible. The climax of this terror bombing was the bombing of Dresden in early 1945, in which the tremendous heat generated by the bombs created a vacuum into which fire leaped swiftly in a great firestorm through the city. More than 100,000 died in Dresden. (Winston Churchill, in his wartime memoirs, confined himself to this account of the incident: "We made a heavy raid in the latter month on Dresden, then a centre of communication of Germany's Eastern Front")

The bombing of Japanese cities continued the strategy of saturation bombing to destroy civilian morale; one nighttime fire-bombing of Tokyo took 80,000 lives. And then, on August 6, 1945, came the lone American plane in the sky over Hiroshima, dropping the first atomic bomb, leaving perhaps 100,000 Japanese dead, and tens of thousands more slowly dying from radiation poisoning. Twelve U.S. navy fliers in the Hiroshima city jail were killed in the bombing, a fact that the U.S. government has never officially acknowledged, according to historian Martin Sherwin (A World Destroyed). Three days later, a second atomic bomb was dropped on the city of Nagasaki, with perhaps 50,000 killed.

The justification for these atrocities was that this would end the war quickly, making unnecessary an invasion of Japan. Such an invasion would cost a huge number of lives, the government said-a million, according to Secretary of State Byrnes; half a million, Truman claimed was the figure given him by General George Marshall. (When the papers of the Manhattan Project-the project to build the atom bomb- were released years later, they showed that Marshall urged a warning to the Japanese about the bomb, so people could be removed and only military targets hit.) These estimates of invasion losses were not realistic, and seem to have been pulled out of the air to justify bombings which, as their effects became known, horrified more and more people. Japan, by August 1945, was in desperate shape and ready to surrender. New York Times military analyst Hanson Baldwin wrote, shortly after the war:

The enemy, in a military sense, was in a hopeless strategic position by the time the Potsdam demand for unconditional surrender was made on July 26.

Such then, was the situation when we wiped out Hiroshima and Nagasaki.

Need we have done it? No one can, of course, be positive, but the answer is almost certainly negative.

The United States Strategic Bombing Survey, set up by the War Department in 1944 to study the results of aerial attacks in the war, interviewed hundreds of Japanese civilian and military leaders after Japan surrendered, and reported just after the war:

Based on a detailed investigation of all the facts and supported by the testimony of the surviving Japanese leaders involved, it is the Survey's opinion that certainly prior to 31 December 1945, and in all probability prior to 1 November 1945, Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated.
