The age-old advice: Do something.

CNN reports:

A pair of suspected U.S. drone strikes killed four al Qaeda militants in Yemen as the United States maintained a heightened security alert in the country and urged all Americans to leave immediately.... A Yemeni official said four drone strikes have been carried out in the past 10 days....

It is unclear whether the strikes were related to the added security alert in the country after U.S. officials intercepted a message from al Qaeda leader Ayman al-Zawahiri to operatives in Yemen telling them to "do something."

Oh, so it's al Qaeda leader Ayman al-Zawahiri who gave out the call to "do something" — not somebody somewhere in the Obama administration. Noted.
