World War II was the most devastating total war in human
history. Germany, Italy, and Japan had been utterly
defeated. Perhaps as many as forty million people—soldiers
and civilians—had been killed in only six years. In
Asia and Europe, cities had been reduced to rubble, and
millions of people faced starvation as once fertile lands
stood neglected or wasted. Untold millions of people had
become refugees.
What were the underlying causes of the war? One direct
cause was the effort by two rising capitalist powers,
Germany and Japan, to make up for their relatively late
arrival on the scene to carve out their own global empires.
Key elements in both countries had resented the
agreements reached after the end of World War I that divided
the world in a manner favorable to their rivals and
hoped to overturn them at the earliest opportunity. Neither
Germany nor Japan possessed a strong tradition of
political pluralism; to the contrary, in both countries, the
legacy of a feudal past marked by a strong military tradition
still wielded strong influence over the political system
and the mind-set of the entire population. It is no
surprise that under the impact of the Great Depression,
the effects of which were severe in both countries, fragile
democratic institutions were soon overwhelmed by militant
forces determined to enhance national wealth and
power.
Unlike World War I, which has often been blamed on
the entire system of balance of power politics, the consensus
is that responsibility for World War II falls squarely
on the shoulders of leaders in Berlin and Tokyo who were
willfully determined to reverse the verdict of Versailles
and divide the world between them. The bitterest controversy
to come out of World War II was thus less how it
began than how it ended. Truman’s decision to approve
the use of nuclear weapons to compel Japan to surrender
has often been criticized, not only for causing thousands
of civilian casualties but also for introducing a frightening
new weapon that could threaten the future survival of the
human race. Some analysts have even charged that Truman’s
real purpose in ordering the nuclear strikes was to
intimidate the Soviet Union. Defenders of his decision
argue that the human costs of invading the Japanese
home islands would have been infinitely higher had the
bombs not been dropped, and the Soviet Union would
have had ample time to consolidate its control over
Manchuria. More than half a century later, that debate
has not yet come to an end.
Whatever the causes of World War II and its controversial
conclusion, the consequences were soon to be evident.
European hegemony over the world was at an end,
and two new superpowers on the fringes of Western civilization
had emerged to take its place. Even before the
last battles had been fought, the United States and the
Soviet Union had arrived at different visions of the postwar
world. No sooner had the war ended than their differences
gave rise to a new and potentially even more
devastating conflict: the Cold War. Though Europeans
seemed merely pawns in the struggle between the two
superpowers, they managed to stage a remarkable recovery
of their own civilization. In Asia, defeated Japan
made a miraculous economic recovery, and the era of European
domination finally came to an end.
