Shooting first and asking questions later has never been a good foreign policy. The past year has been a perfect example.

In September President Obama and many in Washington were eager for a U.S. intervention in Syria to assist the rebel groups fighting President Bashar Assad's government. Arguing against military strikes, I wrote that "Bashar Assad is clearly not an American ally. But does his ouster encourage stability in the Middle East, or would his ouster actually encourage instability?"

The administration's goal has been to degrade Assad's power, forcing him to negotiate with the rebels. But degrading Assad's military capacity also degrades his ability to fend off the Islamic State of Iraq and al-Sham. Assad's government recently bombed the self-proclaimed capital of ISIS in Raqqa, Syria.

To interventionists like former Secretary of State Hillary Clinton, we would caution that arming the Islamic rebels in Syria created a haven for the Islamic State. We are lucky Mrs. Clinton didn't get her way and the Obama administration did not bring about regime change in Syria. That new regime might well be ISIS.
