I can easily see a Soviet boss using captured Western technology to advance Soviet might. It happened in real life, quite often (Nuclear weapons program, rockets, etc...)
But as someone who grew up in USSR, the idea that anyone in USSR would want ana Americancitizen of the USA, of all people, to be the "superhero" Winter Soldier, seems to stretch credibility.
I can see why Hydra would want to use Barnes (they care about Hydra, not the EverLasting Glory of The Homeland of Elephants). But any non-Hydra USSR boss approving the idea... well, that seems way too far-fetched even in a universe that has a talking intelligent Racoon.
Is there any in-universe explanation why ana AmericanUS citizen was used, instead of a proper RussianSoviet citizen (like for Red Guardian program, for example)?
I'm OK with either MCU-specific, or comic Marvel answers
