Striking Syria Again Would Be a Grave Mistake for America (and President Trump)

America faces two grave consequences if the president unilaterally attacks Assad.

The first day of a new job is always rough. But pity incoming National Security Advisor John Bolton, who will probably not even have time to unpack. His first crisis has arrived before he has. Dozens of civilians are dead east of Damascus, apparently killed in a chlorine gas attack by the Assad regime. Footage circulating on social media shows the dead packed in a basement shelter: men, women, children, all lifeless.

Bolton’s new boss tweeted Sunday that there was a “big price to pay” and suggested that Barack Obama should have snuffed out “Animal Assad” during a similar crisis five years ago. The Joint Chiefs of Staff are reportedly set to present Trump with military options against Syria. We may see a rerun of the cruise missile strike last year on a Syrian air base. If this happens, few will shed tears for Assad’s men. But a strike would be a double error for the United States. First, it would not address a vital U.S. national security interest. Our military strength can deter similar attacks on America. Second, a strike would erode the rule of law here at home. Under the Constitution, the president does not have the power to initiate war. The Syria threat is not so serious that we should break our laws to address it.

War and death in a far corner of the world do not automatically threaten vital U.S. national interests. Our “detached and distant situation,” to borrow a phrase from George Washington, means that we rarely face direct threats to our territory, to our fundamental prosperity, or to the independence and openness of our government. We have no strong neighbors that are about to invade us. Threats to the United States tend to be indirect: for example, Al Qaeda, under the protection of the Taliban, plotted attacks against America from Afghanistan. In the early Cold War, the Soviet Union had the potential to sweep into war-ravaged Western Europe. Had it dominated that region’s vast population and economic potential, it could have challenged America on the global stage and even projected serious power into our hemisphere.

Bashar al-Assad can barely dominate the Damascus suburbs, much less amass the power for a direct attack on America. Russia and Iran have gained influence in Syria by backing Assad. But they, too, are unlikely to turn Syria into a dagger at America’s throat. Divided and in ruins, Syria is a liability to whomever owns it. That won’t change for some time. Any threat to America from Syria, and from gas attacks in Syria, has to be very indirect.

Those who want to strike Assad again argue that there is an international norm against the use of chemical weapons and that this norm makes it less likely that chemical weapons will be used against Americans. If “the international community,” which in this context means “the U.S. military,” looks the other way at chemical attacks, chemical weapons will come to be used more frequently in war. They then may eventually be used against American troops or even American civilians. Sohrab Ahmari made this argument succinctly in Commentary on Sunday morning: “Intervention is necessary to deter use of illegal weapons. If [Assad] gets away with it, as he has (mainly owing to Obama’s pusillanimity), other nasty regimes will conclude that they can, too. That will eventually threaten Western security.” Ahmari brands this “Boltonian realism.”

Yet realism weakens the case that strikes on Syria are necessary to nip in the bud a long chain of events that ends in tangible harm to America. Realists share Bolton and Ahmari’s dim estimation of human nature. States act on self-interest and do not follow the niceties favored by those Bolton scornfully calls the “High-Minded.” Bad, norm-breaking behavior is likely if it yields benefits. As the ur-realist Thucydides put it, "the strong do what they can and the weak suffer what they must." Assad knows we, too, are strong. His self-interest and our strength intersect to deter him from using his chemical weapons against us, lest he face our vengeance. Fear of retaliation, not norms, kept the Germans, Italians, and Japanese—all enthusiastic gassers of weaker foes—from using the weapons against the Western Allies in World War II. Recent incidents outside Syria—in which advanced chemical weapons were used for assassination—were conducted by states whose nuclear deterrents make retaliation hard and whose targets had little power projection capability. The United States need only speak softly and continue to carry its big stick to deter chemical strikes on itself.
