The corridor that goes westward from Mosul, crossing the unstable Syrian border and leading to Damascus from there, is now the heart of the Middle East war.
The imminent defeat of ISIS in Mosul (the Iraqi army has freed most of the city and is now fighting for the last four square kilometers) and Raqqa (where the Syrian Democratic Forces, SDF, have surrounded the “capital” of the Caliphate on three sides) will leave room for a regional settling of accounts.
This settling is being negotiated at the tables of Middle East diplomacy where Trump was seated with full honors: The enemy is Iran and the Tehran-Baghdad-Damascus corridor.
The table is being set by the Sunni front, to which the new U.S. administration has provided the necessary weaponry ($110 billion in sales contracts with Riyadh). Weapons have never been denied in the past and, with them, the petro-monarchies have promoted the jihadist activities.
