Had they both gone after Stalin first perhaps the world would have been divided into three spheres of influence with Germany running Europe, Japan running Asia and the USA running the Western Hemisphere. In that case 2/3rd’s of the world would have been in the grip of dictatorships.
Instead America became the world leader with the Soviet Union a distant second. This meant that 2/3rd’s of the world was living in democracies. Today democracies are in a far more dangerous place because of world’s ability to fight a truly global war.
Moving forward will the world become all democratic or all dictatorial! As both China and Asia emerge onto the world stage one has to consider whether the Asian cultural preference for consensus will lean one way or the other! Will see.
And that is all I have to say about!
