The Obama administration’s plan to launch a military strike against Syria is being received with serious reservations by many in the U.S. military, which is coping with the scars of two lengthy wars and a rapidly contracting budget, according to current and former officers.

Having assumed for months that the United States was unlikely to intervene militarily in Syria, the Defense Department has been thrust onto a war footing that has made many in the armed services uneasy, according to interviews with more than a dozen military officers ranging from captains to a four-star general.

Former and current officers, many with the painful lessons of Iraq and Afghanistan on their minds, said the main reservations concern the potential unintended consequences of launching cruise missiles against Syria.

Some questioned the use of military force as a punitive measure and suggested that the White House lacks a coherent strategy. If the administration is ambivalent about the wisdom of defeating or crippling the Syrian leader, possibly setting the stage for Damascus to fall to fundamentalist rebels, they said, the military objective of strikes on Assad’s military targets is at best ambiguous.

“There’s a broad naivete in the political class about America’s obligations in foreign policy issues, and scary simplicity about the effects that employing American military power can achieve,” said retired Lt. Gen. Gregory S. Newbold, who served as director of operations for the Joint Chiefs of Staff during the run-up to the Iraq war, noting that many of his contemporaries are alarmed by the plan. […]

Still, many in the military are skeptical. Getting drawn into the Syrian war, they fear, could distract the Pentagon in the midst of a vexing mission: its exit from Afghanistan, where U.S. troops are still being killed regularly. A young Army officer who is wrapping up a year-long tour there said soldiers were surprised to learn about the looming strike, calling the prospect “very dangerous.”

“I can’t believe the president is even considering it,” said the officer, who like most officers interviewed for this story agreed to speak only on the condition of anonymity because military personnel are reluctant to criticize policymakers while military campaigns are being planned. “We have been fighting the last 10 years a counterinsurgency war. Syria has modern weaponry. We would have to retrain for a conventional war.”
