One of the ways to improve the game feel for the USA is the Cabinet Ministers screen.
The US uses the term ‘Secretary’ for most cabinet positions rather than the term ministers, and they have different names. See https://en.wikipedia.org/wiki/Cabinet_of_the_United_States. They don’t all map precisely, but for example:
- Law and Order Minister could be Secretary of Homeland Security; and
- Chancellor could be Secretary of the Treasury.
The USA executive does not have to come from parliament either, the President gets to pick who ever he likes and the senate confirms them. So the ‘potential ministers’ list could be a lot longer and not just the same old names, see https://en.wikipedia.org/wiki/Cabinet_reshuffle
