Getting back to France, I would like to point out that they had an impressive number of ships still under construction in 1918, and with the release of the shipwrights from the front (talk about a ludicrous draft policy), they could have had a reasonable force by 1922. Meanwhile, they discussed and debated and deliberated and in the end nothing was done.
Fortunately for France, George Leygues and Francois Petric were able to create a first-class navy by the late '30s. What a shame they were let down by their national leaders.
I think given the internal political situation in France, a carefully guided German policy, perhaps with the aid of sympathetic America, (remember, Charles Lindbergh was openly pro-Nazi, and Henry Ford was awarded the "Great Order of the German Eagle") could have circumvented the Versailles treaty and left Weimar Germany in the hands of MODERATES by the mid 1930s.
Even if France felt provoked, and occupied the Rhineland, it would be their equivalent of the "West Bank", and they would have withdrawn in months. It probably would also have required the recall, transport and sustenance of Colonial troops from Africa, which would be politically untenable.

If an unfriendly power had attempted to impose on America the mediocre educational performance that exists today, we might well have viewed it as an act of war.
