A quiet meeting this past March in Saudi Arabia, and a recent anonymous leak from the Israeli military, set the stage for what may be a new and wider war in the Middle East.
Gathering in the Saudi Arabian capital of Riyadh were Turkish President Recep Tayyip Erdogan, newly crowned Saudi King Salman, and the organizer of the get-together, the emir of Qatar. The meeting was an opportunity for Turkey and the Saudis to bury a hatchet over Ankara's support -- which Riyadh's opposes -- to the Muslim Brotherhood, and to agree to cooperate in overthrowing the Syrian government of Bashar al-Assad.
Taking Aim at Assad
The pact prioritized the defeat of the Damascus regime over the threat posed by the Islamic State and al-Qaeda, and aims to checkmate Iranian influence in the region. However, the Turks and the Saudis are not quite on the same page when it comes to Iran: Turkey sees future business opportunities when the sanctions against Teheran end, while Riyadh sees Iran as nothing but a major regional rival.
The Turkish-Saudi axis means that Turkish weapons, bomb-making supplies, and intelligence, accompanied by lots of Saudi money, are openly flowing to extremist groups like the al-Qaeda associated Nusra Front and Ahrar al-Sham, both now united in the so-called "Army of Conquest."
The new alliance has created a certain amount of friction with the United States, which would also like to overthrow Assad but for the time being is focused on attacking the Islamic State and on inking a nuclear agreement with Iran. This could change, however, because the Obama administration is divided on how deeply it wants to get entangled in Syria. If Washington decides to supply anti-aircraft weapons to the Army of Conquest, it will mean the United States has thrown in its lot with Turkey, Saudi Arabia, and Qatar, and that the "war on terror" is taking a backseat to regime change in Syria.
Not that the Americans are overly concerned about aiding and abetting Islamic extremists. While the U.S. is bombing the Islamic State in Iraq and Syria, the Obama administration is also training Syrians to overthrow Assad, which objectively puts them in the extremist camp vis-a-vis the Damascus regime. Washington is also aiding the Saudis' war on the Houthis in Yemen. Yet the Houthis are the most effective Yemeni opponents of the Islamic State and the group called Al-Qaeda in the Arabian Peninsula, against which the United States is waging a drone war.
The Turkish-Saudi alliance seems to have already made a difference in the Syrian civil war. After some initial successes last year against divided opponents, the Syrian government has suffered some sharp defeats in the past few months and appears to be regrouping to defend its base of support in the coastal regions and the cities of Homs, Hama, and Damascus. While the Syrian government has lost over half of the country to the insurgents, it still controls up to 60 percent of the population.
