West Germany had a similar culture to their occupant, the east not so much. Germany also became the centrepiece for a US vs. Russia proxy war, Syria would likely become the same and is arguably already in that state.

In any case it would depend on whether a post WWIII and independent(ish) Syria, much like the post WWII Germany, makes the prudent decision to outlaw and taboo the fanaticism that got it into that situation in the first place.
