Not only do those particular prior assumptions date to 1957 in a way that makes deviating from them structurally dangerous, they involve very low military spending in a way that makes deviating from them politically dangerous.

Fixing the budget hole to pay for that spending without resorting to giving many people living in Monaco the Eichmann treatment as a side effect (which is untenable on account of French security guarantees to Monaco) would need some kind of government of hardcore believers who could also do math.
