Japanese history demonstrates that you're likely to get somebody killing you if you try a move like that. Being anything other than a super patriot at this time period is to open yourself up to suspicion and maybe imprisonment. And so right around the time the germans attack the soviet union, the japanese sort of move into the rest of french, indo china, lous cambodia, viet nam. So now it's not just about cutting japan off. It's about japan cutting the united states off from things they need. This is when the serious sanctions start.
