In theory, sanctions are a non-violent method of persuasion. That is not what is happening in Syria.

US-led forces have blown up three oil tankers in Syria as the United States increases its pressure on Syria by thwarting the oil trade between the PKK/YPG and the Assad regime, according to local sources quoted by several media sources.

The strike was carried about by coalition planes, which hit three oil tankers, leaving four dead. The coalition has not yet made a statement about the attack. In the area controlled by Assad, oil consumption stands at around 136,000 bpd. Production, meanwhile, is only 24,000 barrels per day. This means that the regime must import significant volumes of crude oil at an estimated expense of more than $2 billion per year.

Bombing transport of needed supplies isn't sanctions. It's a siege.

n Syria, Arab residents of oil-rich Deir Ezzor area began protests in April against US-backed Kurdish forces that control the region to the East of the Euphrates. The protests disrupted the oil flows from nearby fields, most of which have been controlled by the US-backed Syrian Democratic Forces since the end of 2017.

The fuel and electricity shortages that are occurring now in Syria have soured previous supporters of Assad against his rule.

When the Assad forces were about to drive ISIS from Deir Ezzor, we pushed the Kurdish SDF to take this non-Kurdish region first. Why? Because of the oil.
And now the Arabs are being ruled by the Kurds, who don't like it.
