If you can see enough of what an intelligence apparatus is doing to be impressed I'd say they're not doing a very good job.

What they seem to be most unique in is the impunity of their operations, like when they assassinated a completely innocent guy in Norway, of all places: https://en.wikipedia.org/wiki/Lillehammer_affair

The best intelligence apparatus in the world missed the Oct 7 planning which Egyptian intelligence noticed, told the Israelis about directly, and still went ignored?
