Fareed Zakaria:

But the truth is this is a huge, devastating blow to al Qaeda, which had already been crippled by the Arab Spring. It is not an exaggeration to say that this is the end of al Qaeda in any meaningful sense of the word. ... With the death of bin Laden, the central organizing ideology that presented an existential seduction to the Muslim world and an existential threat to the Western world is damaged beyond repair. We’re left with free-lance terrorists who will, of course, be able to inflict some harm. But the Somali pirates are able to inflict harm on civilians, and that doesn’t turn them into an existential threat to the Western world. That existential threat is gone.
