In June, the United States imposed new sanctions on Syria: a “sustained campaign of economic and political pressure” to end the nine-year war by forcing President Bashar al-Assad to U.N.-brokered peace talks where he would negotiate his departure from power. Assad’s wife was already cross about not being able to shop at Harrod’s or Bergdorf Goodman, so he should crumble any day now.

Other things are crumbling already. Ordinary people’s incomes are collapsing (down by three-quarters since the beginning of the year). The price of food in Syria has doubled. Lebanon next-door, already in financial meltdown, is now seeing its large trade with Syria vanish as well.

The U.S. decision to raise the pressure on Assad is probably a random byproduct of Donald Trump’s obsessive campaign against Iran (which has been helping the Syrian regime to stay afloat). If Trump even knows that the remaining rebel groups in Syria are by now all led by fanatical Islamists linked to al-Qaida, the group that organized the 9/11 terrorist attacks, he doesn’t care.

The Syrian tragedy is mainly due to endless foreign interventions. The Syrians who called for an end to Assad’s regime in the Arab Spring of 2011 were just like the young men and women who started demanding the fall of Egyptian dictator Hosni Mubarak at the same time. They were both genuinely popular movements, not fronts for jihadis.

The Egyptian protesters won, there was a free election — and then the army struck back in 2013, slaughtered several thousand people in the streets of Cairo and put General Abdel Fatah el-Sisi in power, where he remains to this day. Egypt is at peace, although hundreds more people have probably died in Sisi’s prisons since then and thousands have been tortured.

The Syrian protesters didn’t get that far. They were driven from the streets — but then various foreign powers started organizing the rebels and giving them arms. The war has lasted another eight years, and somewhere between 400,000 and 700,000 Syrians have been killed. Five million Syrians have fled abroad, and another 5 million are displaced within Syria.

So here’s the question: would you prefer Egypt’s fate or Syria’s? Both countries are still tyrannies, but one is literally in ruins, with half the population out of their homes, and the other had a few thousand deaths. It’s a no-brainer, isn’t it?

The Syrian power struggle would probably have ended in an Assad victory around the same time that Sisi took over in Egypt if the U.S., Turkey and Saudi Arabia hadn’t begun sending the Syrian rebels arms and money. U.S. motives were mixed, but the Turks and the Saudis, both led by different kinds of militant Muslims, just saw an opportunity to replace a secular regime with a hard-line Islamist one.

They would probably have succeeded if Russia had not intervened to save Assad in 2015, and Syria would probably be divided today between al-Qaeda and Islamic State. The groups linked to al-Qaida absorbed or destroyed all the others, and today they rule over a single province in Northwest Syria under Turkish protection. But still the war drags on.

When governments impose sanctions they usually explain that they had to “do something,” but the new sanctions will hurt ordinary Syrians very badly. They might be justified if there were a reasonable chance that more sanctions could bring Assad’s regime down, but there’s no chance of that, and everybody knows it.

In a famous paper in 1997, Robert Pape of the University of Chicago showed that out of 116 cases of international sanctions being imposed during the 20th century, in only six cases did the target government yield to the demands of the country imposing the sanctions. The success rate has not improved since.

It has been 70 years since the United States imposed sanctions on North Korea, and the Kim family is still in power. It has been 60 years since it put sanctions on Cuba, and the Communists still rule. It has been 40 years since Washington slapped sanctions on Iran, and the ayatollahs still rule. Not to mention Zimbabwe (sanctions since 2003), Venezuela (2006), or Russia (2014).

“Doing something” feels good, but it doesn’t usually do much good.
