What Ayman al-Zawahiri’s killing means for al-Qaeda

Ayman al-Zawahiri, the leader of al-Qaeda and one of the world’s most wanted terrorists,

The 71-year-old was largely considered the brains behind the notorious terrorist group

and its vision for attacking the West — including the attacks of Sept.

which catapulted al-Qaeda from relative obscurity to a household name in the United States.

President Biden said in an address to the nation Monday that Zawahiri’s death

after he evaded capture for decades — sent a clear message:

“No matter how long it takes, no matter where you hide,

if you are a threat to our people, the United States will find you and take you out.”
