How do you solve a problem like Syria?

[Indy Texas 🇺🇦🇵🇸]

Through a complex and unusual set of circumstances, you find yourself the head of the Syrian government and have managed to secure military control over the entire country. The civil war is over. As head of a transitional governing council, you are the de facto leader of Syria and have absolute authority over any public decisions. Under terms agreed to by all parties at the end of the conflict, no elections can be held for at least five years. You cannot resign, as that would create a succession crisis and potentially cause the civil war to resume. What do you do to maintain order and best ensure long term stability for the country?

Caveats:
(1) ISIS still exists, but only exercises control over areas of Iraq. However, non-militarized political groups affiliated with ISIS do exist in Syria. 
(2) The anti-Assad factions' demands are largely moot for obvious reasons, but they are not loyal to you either and will not necessarily be amenable to your actions.
(3) Bashar and Asma Assad have fled the country and are living in exile in Paris. The other Assad family members are in exile abroad as well and none have any intention of ever returning to Syria. However, many of their allies are still in the country and seek to get or maintain political influence.

Nationalize all private and foreign assets and gradually devolve them to worker control wherever possible, guarantee equal legal rights for all religious/ethnic groups, establish a massive development project for poorer/more rural areas of the country, end discriminatory policies against women and homosexuals, form wide-scale propaganda campaign promoting equality and acceptance. It would either be a smashing success or go down in flames.

The Arab/Islamic world had its brief flirtation with Marxism-Leninism in the form of the People's Democratic Republic of Yemen.

Syria, in fairness, has actual natural resources besides sand.

I would imagine you'd still wind up needlessly provoking the Islamists, both in and out of the country. The only successful implementations of communism in countries with Muslim majorities were the Central Asian Soviet republics and Albania under Enver Hoxha - and both cases involved brutal suppression of any religious expression.
