Osama bin Laden is dead. But revolutionary Islamism is very much alive and stronger than ever. Thinking that bin Laden is the main problem and his death is the solution is very dangerous indeed and might well intensify the policies that have been leading toward the victory of his cause, though not his specific movement.

It is easy to forget that when bin Laden came on the scene revolutionary Islamism was in retreat. True, Iran was ruled by a revolutionary Islamist regime but that government had failed to extend the revolution overseas very much despite its best efforts. Another such regime, the Taliban, came to power in remote Afghanistan.

But by the end of the 1990s, revolutionary Islamism wasn’t doing so well. The reason was that its strategy was to overthrow Arab governments from within. There had been civil wars in Algeria, Egypt, Lebanon, and to a lesser extent in other places. The existing dictatorships, however, had repressed them.

So bin Laden came along with a different approach. If direct attacks on non-Islamist governments in Muslim-majority countries didn’t work, he proposed an international movement that would raise revolutionary enthusiasm by attacking the West.
