In the US, we are taught in school and in all of our media that we were somehow the "tipping point." This is determined, in the European theater, by being involved peripherally and not participation in actually defeating the enemy (which had been relentlessly throwing itself against its eastern front) - we had to rush to try to meet the Soviets in Berlin despite much easier conditions. And in the Pacific theater, we Americans are taught that victory was determined by "awesome A-bombs" instead of what the actual timing shows to be - "oh, crap - Stalin," causing Japanese surrender to anyone but Stalin. The US POV is exported to everywhere else via Hollywood, thus global propaganda, a global "campaign."
That said, this is a puff piece in Vox. What do you expect?
