My questions have to do with our policies pre-Pearl Harbor, not the waging of the war post-Pearl Harbor.
Adams, I'm not an Adams expert, but the Alien and Sedition Acts are worth mentioning. Basically laws making it illegal to print "False information" about the President or Congress. It was used often against political opponents. To be fair, early Presidents, including Adams, usually refrained from vetoes unless the law was though to be unconstitutional, and not for mere disagreement. It is also the case that Adams did oppose the law in question. He still signed the clearly unconstitutional legislation though. Adams did, however, avoid war with Britain and wisely followed Washington's foreign policy. All in all, Adams was a fairly pathetic President, but he wasn't outright evil like Lincoln, Wilson, either Roosevelt, or their ilk.
