The war for northern Syria has entered a new, grinding phase. On December 15, 2024, the Syrian Democratic Forces launched a major offensive in eastern Aleppo. Their target is territory held by the Turkish-backed Syrian National Army. This is not a sudden eruption. It is the latest chapter in a conflict that has simmered since the fall of the Assad regime, a power struggle between the Democratic Autonomous Administration of North and East Syria and the Turkish state.
The immediate trigger is the Manbij offensive. The SDF lost ground there. Now they are trying to take it back. The operation is aimed at securing those lost areas and pushing forward into the Tishrin Dam area from Dayr Hafir. The dam is the prize. It spans the Euphrates River. Control of it means control over water and electricity for a huge swath of the region. That is not abstract. That is survival. The SNA knows this. They will fight hard. Turkey backs them with military might.
This is a landscape of shifting alliances and old hatreds. The SDF is backed by the United States. They have been Washington’s most reliable partner on the ground against extremist groups. The SNA is Ankara’s proxy. Turkey sees the SDF as an extension of the PKK, a group it has been fighting for decades. The two sides have never been close. The collapse of the Assad government removed the one central authority that had kept a lid on some of these rivalries. Now the lid is off.
The SDF’s push into the Tishrin Dam area is not just about territory. It is about leverage. The dam is a strategic asset. Whoever holds it can dictate terms. The 10 March agreement, signed earlier this year, stated that the dam and its surrounding areas were supposed to be joint. That deal is now dead. The offensive killed it. The SDF is betting that a military solution will work where diplomacy failed.
It is a risky bet. Turkey has not been shy about using its own military power in Syria. It has launched multiple incursions over the years. The SNA is not a disciplined national army, but it is well-armed and motivated. The SDF is battle-hardened. They have fought ISIS, the Assad regime, and Turkish forces before. They know the ground. That matters in a fight like this. The terrain around Dayr Hafir is open, flat. Cover is scarce. Armor and air power will decide things.
The international community is watching. That is a polite way of saying nobody is intervening yet. The United States has not made a public move. Turkey has condemned the offensive. The SDF has framed it as a defensive operation. Neither side is backing down. The battle for the Tishrin Dam will shape the next phase of this war. If the SDF takes it, they consolidate control over the eastern Euphrates. If the SNA holds, the SDF is pushed back, weakened.
This is not a clean war. It is a war of militias, of foreign backers, of local grievances. The fall of the Assad regime did not bring peace to Syria. It just rearranged the enemies. The SDF and the SNA are both products of that collapse. They are fighting over the scraps of a broken state. The Tishrin Dam is the biggest scrap left. The water and the power it provides are the difference between a functioning region and a dead one. That is what is at stake in eastern Aleppo. That is why this offensive matters.
