They are tired of wannabe soldiers who remain enamored of the lure of bloodless machine warfare. “Look,” one told me, “if you want to end this decisively, send in the troops and let them defeat the Syrian army. If the nation doesn’t think Syria is worth serious commitment, then leave them alone.” But they also warn that Syria is not Libya or Serbia. Perhaps the United States has become too used to fighting third-rate armies. As the Israelis learned in 1973, the Syrians are tough and mean-spirited killers with nothing to lose.

Our military members understand and take seriously their oath to defend the constitutional authority of their civilian masters. They understand that the United States is the only liberal democracy that has never been ruled by its military. But today’s soldiers know war and resent civilian policymakers who want the military to fight a war that neither they nor their loved ones will experience firsthand.

Civilian control of the armed services doesn’t mean that civilians shouldn’t listen to those who have seen war. Our most respected soldier president, Dwight Eisenhower, possessed the gravitas and courage to say no to war eight times during his presidency. He ended the Korean War and refused to aid the French in Indochina; he said no to his former wartime friends Britain and France when they demanded U.S. participation in the capture of the Suez Canal. And he resisted liberal democrats who wanted to aid the newly formed nation of South Vietnam. We all know what happened after his successor ignored Eisenhower’s advice. My generation got to go to war.
