3) A follow up on the previous question - how many intelligence organizations are actually involved in gathering intelligence about terrorist activity in Western nations, as well as the wars in Afghanistan and Iraq? I've heard practically nothing about the involvement of intelligence organizations from outside of the USA and UK. Yet that doesn't sound right - so many countries are involved in these wars that one would think they all have a vested interest in gathering intelligence.
The great thing about intelligence organisations is that you don't really know.
At some point a few years ago the German BND had trojans in the computer network of some Afghan ministry.
For the most part you only know that an intelligence agency is involved when they screw up.
If you also count private intelligence companies I wouldn't be surprised if more than hundred different organisations are involved in gathering that kind of intelligence and that no single person exists who knows all of those organisations.
