France simply has to enforce the military part of the treaty. The moment Germany intoduces concription just send a couple divisions to pay Hitler a visit in Berlin.
Actually those would have only needed to get to Aachen and Hitler folds.
For the economical part just do a reverse Frankfurt. Scrap all the parts that seriously hampered German trade (confiscation of merchant marine, scrapping patents and trade marks, no one sided most favored nation status)
and as you are at it scrap the pages with the hundreds of nitty gritty points…
and occupy the Rhineland (not the Ruhr for heavens sake) until Germany did pay. A hefty amount but one there is a clear reachable end to it.
Oh and of course as in revers Frankfurt, leave Germany the ability to have means to pay. And of course any confiscated German possession counts as payment.
And before someone screams of course add it to the bill upfront so you end up with the same money but a much more palatable treaty.
