SURPRISE quiz: Is Al Qaeda Sunni or Shiite? Which sect dominates Hezbollah?

Silvestre Reyes, the Democratic nominee to head the House Intelligence Committee, failed to answer both questions correctly last week when put to the test by Congressional Quarterly. He mislabeled Al Qaeda as predominantly Shiite, and on Hezbollah, which is mostly Shiite, he drew a blank.

“Speaking only for myself,” he told reporters, “it’s hard to keep things in perspective and in the categories.”

Not that he’s alone. Other members of Congress from both parties have also flunked on-the-spot inquiries. Indeed, some of the smartest Western statesmen of the last century have found themselves flummoxed by Islam. Winston Churchill — in 1921, while busy drawing razor-straight borders across a mercurial Middle East — asked an aide for a three-line note explaining the “religious character” of the Hashemite leader he planned to install in Baghdad.

“Is he a Sunni with Shaih sympathies or a Shaih with Sunni sympathies?” Mr. Churchill wrote, using an antiquated spelling. (“I always get mixed up between these two,” he added.)
