People who are distinguishing them here are relying on peculiar definitions of these terms, which are largely peculiar to Americans-and I’d add, only some of them.
To an Australian or Briton or Canadian or New Zealander, “Republic” means not being a constitutional monarchy. I think it means something similar in a lot of other countries. Australia is a democracy but not a republic, because it has a King instead of a President. The US, France, Germany, Ireland, Israel (putting aside the Palestinian issue) are democratic republics, because they are democracies with Presidents instead of a King/Queen. China or North Korea are republics but not democracies; Saudi Arabia is neither a republic nor a democracy.
