“Well, we can use another metric to help you out in understanding it ... :-) ...
When we start approaching a significant fraction of the dead as we got in World War II, then you might have something worthy of the name “World War”.
World War II had over 60 million dead as a result of that war. So, let’s say that we can “start getting suspicious” that we have something that is called a “World War” when we pass a threshold of 20% — in other words, about 12 million dead as a result of the war! Then if another year goes by and we have another 12 million dead as a result of the war (making it 40% of before) then pretty much everyone in the world will be using the name “World War” ... :-) ...
By the time we get to the end, we will have definitely reached 60 million or more, so NOBODY will be quibbling about the label “World War”.”
Star Traveler, your are correct on your percentages and human calculations. But this WWIII (and if you think WWII was not this same battle... what can one do?) is not a battle of human flesh and blood. It is a battle against the rulers of evil and the Power of G-d.
Okay ... in those terms then ... when I see 2/3 of the world’s population dead, from the events described in the book of Revelation, then I’ll be happy to use the phrase “World War” ... :-) ...
