In Morocco there is a swamp of sub-identities, but there is a common base that they can use in order to reconstruct a national identity.
And thats something they have to figure out themselves, instead of saying that they lost the identity-battle before even starting it.
That base will always be there, no matter what.
All Moroccans will regard tajine as a heavenly, moroccan dish, for example (silly example, but it might work)

I always admired the way the Turkish state succeeded in forging a national identity from scratch.
Kemalist Turkey was multicultural, even after the Armenian genocide. The flood of Muslim refugees from the Balkan, Greece etc contributed to that.
But nevertheless, they succeeded in creating a Turkish identity ( a very strong one actually)

Colonialism obviously had a profound effect on Morocco, mostly negative (it’s hard to say because we don’t have a “control case”), and cultural colonialsm is still having a corrosive effect as you said in your original post. But I would give the Moroccans more credit that you do for “cultural backbone.” The moment he got off the boat in Tangier, my friend Gilles knew he was in a very different culture. And he never stopped showing his amazement about Moroccan freedom compared to Europe (some of it bad, like the “freedom” of shop owners to employ ten year old boys).

To me, the amazing thing about Morocco is the skill people have at adaptation. “Necessity is the mother of invention” someone said, and there is a lot of necessity in Morocco…! But despite the sarcasm, I mean what I say. Moroccans still have a rich heritage (although it would help to learn more about it—see my earlier post) and an amazing ability to adapt. Those are excellent qualities to have in a globalized world.

I think that to reconstruct identity, we should already have one. But we lost it years ago, by colonization that was added to the regional segregation.

So I think in Morocco, the case is way too difficult to be interpreted as a general one.
