People can cry about MacArthur all they want, act all mighty and sneer and critize a man who was a million times grander than each of them, but if today America rules the world it is because of him. The Europeans, from Lisbon to Vladivostok bow before American Supremacy, Eastern Asia, China and Korea and Japan the Phillipines and Vietnam all follow our lead and are our greatest allies, Africa is developing under our tutelage and the myriad of shitty dictators in South America are dead because of him.
Ah yes, he overthrew the shitty dictators of South America and replaced them with fully functioning democracies with constitutions that have been temporarily suspended while their "Presidents" helped to crack down on "communist remnants" such as farmers, peaceful protestors, and hospital employees.
For all that people feel about MacArthur, it is because of him that we are here today.
In two years our first Moon and Mars colonies will be built and our spaceships will soon reach Jupiter's moons.
It is because of MacArthur endless ambitions that America todays leads humanity in manifesting its destiny over our Solar system. There is no greater achievement than that.
Ah yes, the vast unclaimed tracts of the solar system. Just like how Algeria has dominion over the Sahara and Russia over Sibera. So much space for the taking, but so little in it to take. Just like Algerian and Russian villages in their vast space, these planets and colonies have little and produce little. We've invested, what? 10 Trillion Dollars in the Space Program, for what return? We can't grow crops on any other planet. Transporting twenty billion of those crazy "Martian diamonds" would cost about 50 billion. I'm not advocating for disbanding NASA, but "colonizing" the solar system was done for the same reason Europeans colonized Africa a century and a half ago, to make their name bigger on a map. Great, we reached Jupiter, which is valuable to humanity because _____(you fill in the blank). Same with every other planet past Mars (which isn't exactly a fertile paradise). And unless we dig up Ronald Reagan or another Star Trek actor and ask how they subverted lightspeed, we're not likely to go anywhere else.
You're right. We wouldn't have such incredible space travel today without MacArthur's pet passion. Because it's useless otherwise. Hitler was insane, but it would be possible to grow crops around the Urals. It's easier than doing it on Mars. There is no "living space" in space.
And, frankly, prestige doesn't fix our problems here on earth. Maybe that forty-seven million dollar water purifier meant for the Jamestown colony would be better served in Flint Michigan.
