Sorry Buff you are a good dude but I am gonna have to disagree with you here. If I had to leave my home and family to go fight the Japanese in a brutal war across the Pacific because my country was sneak attack bombed you bet your ass I would jack a katana while there.
And whatever I chose to do with the sword after that is my decision.
It's really up to the current owner... What makes the swords unique is that it's not a theft of the counyry's riches like gold for example - it's directly depriving future generations of a birth right, and directly stealing legacies from families themselves. Those families are also traceable very easily through the markings and inscriptions that get added to the swords through the centuries, and there are charities all.jver Japan that buys these swords and return them where they're supposed to be.
I wrote a much more detailed bunch of facts in the bigger thread... Personally for me it's bad taste - like selling tiger skins or ivory, and it was also illegal to loot the corpses for personal gain back in the day, regardless of what they did to others.
Also hardly any of the original swords stated with the GIs who had no idea to take care of them, and a lot of them degenerated and were simply thrown away, or sold to pawn shops for pennies... Nothing hood came out of stealing those swords apart from giving rich fucks like Dana, who gives around shits about how sacred the swords are, or their history something to hang on their wall.
Also, just FYI the greatest of all of the Japanese katanas was stolen from a battlefield, and nobody knows where it is in America. the thing is worth $67 and it probably rusted away after some GI tried to open a coconut with it and failed to clean it oil the blade, and it got sold for scrap like so many others.
It's a tragedy if you're into swords, which I am.
