*''The Sum of All Fears'' (1991) - [[Israel]] loses a nuke, which is then used by terrorists on an American city. While the main villains are the terrorists, the secondary villains are the liberal presidential administration that seeks to marginalize the US military and foolishly ignores the advice of the more level headed (i.e. - conservative) officials who counsel caution despite the "end" of the Cold War and nearly cause disaster yet again due to their foolish political decisions.

*''Executive Orders'' (1996) - continues where ''Debt of Honor'' left off, with Jack Ryan bumped up to President of the United States, just in time to deal with a new threat in the Middle East.

Further, the book addresses how liberals have corrupted the US tax code to their own benefit and how similar corruption in the American legislature allowed abortion to become federally protected.
