The Trump foreign policy team has been all over the map on what to do next in Syria — topple the regime, intensify aid to rebels, respond to any new attacks on innocent civilians. But when pressed, there is one idea everyone on the team seems to agree on: “The defeat of ISIS,” as Secretary of State Rex Tillerson put it.

Well, let me add to their confusion by asking just one question: Why?

Why should our goal right now be to defeat the Islamic State in Syria? Of course, ISIS is detestable and needs to be eradicated. But is it really in our interest to be focusing solely on defeating ISIS in Syria right now?

Let’s go through the logic: There are actually two ISIS manifestations.

One is “virtual ISIS.” It is satanic, cruel and amorphous; it disseminates its ideology through the internet. It has adherents across Europe and the Muslim world. In my opinion, that ISIS is the primary threat to us, because it has found ways to deftly pump out Sunni jihadist ideology that inspires and gives permission to those Muslims on the fringes of society who feel humiliated — from London to Paris to Cairo — to recover their dignity via headline-grabbing murders of innocents.

The other incarnation is “territorial ISIS.” It still controls pockets in western Iraq and larger sectors of Syria. Its goal is to defeat Bashar al-Assad’s regime in Syria — plus its Russian, Iranian and Hezbollah allies — and to defeat the pro-Iranian Shiite regime in Iraq, replacing both with a caliphate.
