>My point about the Army of England was intended to illustrate the fact that the French posed a real threat.<
Britain posed a real threat to France. I think everything points to the fact that Napoleon thought the Peace of Amiens would last longer than it did and that Britain thought Napoleon's position was weaker than it was.
As for the fundamental goals of the Revolution those were the goals of 1789-1790, and those goals could have been compatible with monarchy (see, Mirabeau). No one thought that, for instance, the Maximum or the Law of Suspects were fundamental goals of the Revolution, but rather temporary measures.
