And that proves what?
That in this day and age companies would be able to do the same?
Obviously it stands in contrast to just that. "How are the mighty fallen, and the weapons of war perished!' (2 Samuel 1:27) refers past glory, but rather than a band of David's to take the place of past warriors and lead to victory, America has elected leaders who have largely traded production capacity to China for cheap goods and votes, and chosen to go to war against God, including baptizing the military in the waters of Wokeism.
You are asking us to compare America's manufacturing capacity during WWII (1941-45), when the country had a population of 140 million - with its population today, which is over a third of a billion?
When our real GPD was about a tenth of what it is now? When semiconductors and solid-state technology and lasers were science-fiction - compared to today?
