This dude fought in Manchuria for the Japanese against the Soviets, fought in Ukraine for the Soviets against the Nazis, fought in France for the Nazis against the allies, before finally getting captured by the allies and moving to the USA where he got American citizenship
What an absolute lad
..a man whose allegiance is run by expedience...
That's kind of an unfair way to put it, it makes it sound like he was some sort of mercenary. The guy was
captured by three successive fascistic military governments, and did what he was told so that he didn't die. It's not like this guy was a
soldier to start with, he was an 18 year old civilian.
Firstly, the Japanese would have just executed him if he refused to serve. You did
not refuse to be conscripted by the Japanese army. There was no prison for conscientious Chinese/Korean objectors. As for the Russians, Stalin-era gulags historically had death rates exceeding 95%. If he'd refused service when told to by the Russians, I imagine his chance of death in the gulag would have markedly increased, to 100%. The Soviets didn't take kindly to
refusing conscription, either.
Finally he got captured by the Nazis. I doubt
they were treating his service as any more "voluntary" than the Japanese or Russians did. If he'd said "no thanks" to the Nazis they probably would have shipped him to one of the death camps.
"..a man whose allegiance is run by expedience..." is unfair since it make it sound like he had some choice. Being forced to follow the commands of people who will otherwise kill you is not "allegiance". He was just a kid who didn't want to die.
