Sorry, OPREV, but the Gospel was NOT preached in the New World, Japan, Australia, etc.
>> made known to All nations for the obedience of faith: <<
There’s a difference between God making his law known to all the world, through nature, and the Gospel being preached to the whole world.
Of course, some people didn't hear the gospel last century either. What about them? Do they get a magic pass and no judgement? Why do only all of the "last" generation have to hear the gospel? Because if they didn't, the same grace afforded to those who didn't hear it in times past wouldn't apply to them?
