The Post-World-War-II world order was dominated by the one WW II major combatant that had only 0.32% of its population (the lowest percentage) killed by the war: the United States. The Soviet Union’s comparable number killed by the war was the highest — it was 13.7% — 42 .8.times higher than America’s. The U.S. was the main force that defeated Japan and so won WW II in Asia. The U.S.S.R., however, was the main force that defeated Germany and so won WW II in Europe. The U.S.S.R. suffered vastly more than did the U.S. to achieve its victory. In addition to suffering 42.8 times the number of war-deaths than did U.S., the U.S.S.R.’s financial expenditures invested in the conflict, as calculated by Jan Ludvik, were 4.8 times higher than were America’s financial expenditures on the war.
Thus, at the war’s end, the Soviet Union was exhausted and in a much weaker condition than it had been before the war. By contrast, the U.S., having had none of the war’s battles occurring on its territory, was (by comparison) barely even scratched by the war, and it was thus clearly and overwhelmingly the new and dominant world-power emerging from the war.

The U.S. Government did not sit on its haunches with its enormous post-war advantage, but invested wisely in order to expand it. One of the first investments the U.S. made after the war was the Marshall Plan to rebuild the European countries that had now become the U.S….
