Real question is: how far could a barely functional illiterate person (knowing only English and the barest of Russian) go in the Russian Army? Would they even take them? Follow up question: what if they’re obese, diabetic, or have other American-sized health issues?
Most Americans in such a situation would wind up defying their ancestors in similar ways. A lot of families in the USA can trace their lineage back to people that fled religious persecution, racial injustice, famine, war, and tyrannical government. Migrating to a dictatorship that is currently drafting/conscripting their populace straight into a shooting war is a monstrous step back from all that.
Nevermind that the Russians have/had nuclear stockpiles aimed at our heads. And the USA has Russia targeted in return. Come to think of it, choosing to be down range of the US is not a good idea in general.
