> Bin Laden’s Al Qaida was very unusual in its long term planning. Most terrorist attacks by other groups have been unsophisticated.

And, IIRC, most recent terrorist attacks have been committed by isolated individuals who radicalized, and they only used means that a motivated regular person could assemble. They didn't have the material backing of any organization sophisticated enough to manufacture a military nerve agent.

Though, I suppose if a specialist like a chemist got radicalized, then we might have a lone-wolf attack with a sophisticated poison.
