President Obama says he is considering a “limited, narrow” military strike against Syria — an aim that many Middle East experts fear overlooks the potential to worsen the violence in Syria and intensify a fight for regional influence between Iran and Saudi Arabia.

Supporters of the president’s proposal contend that a limited punitive strike can be carried out without inflaming an already volatile situation. But a number of diplomats and other experts say it fails to adequately plan for a range of unintended consequences, from a surge in anti-Americanism that could bolster Syria’s president, Bashar al-Assad, to a wider regional conflict that could drag in other countries, including Israel and Turkey.

“Our biggest problem is ignorance; we’re pretty ignorant about Syria,” said Ryan C. Crocker, a former ambassador to Syria and Lebanon, who has served in Iraq and Afghanistan and is dean of the Bush School of Government and Public Service, Texas A&M University.
