>What policies of local legal framework and the bank define as a "rksy customer" might vary completely.

No they don't? Your next sentence demonstrates as much:

> For example many EU banks refuse service to US citizens due to them still being tax liable in their own country and the banks not waiting to deal with that shit

Local jurisdiction makes fuck all difference. Ignoring foreign regulations would be suicidal for a bank which wants to take part in international commerce.

> But working legally in your nations arms industry is not the definition of a risky customer because you're a legal citizen with rights in your own country, your arms company operates legally with all the checks and approvals of the government, and the banks should as well

Any bank picks up a very significant regulatory burden by engaging in transactions with such an entity. The idea that any bank could just assume that an arms manufacturer is fully compliant because the Czech government allows them to exist is hilarious.
