Sorry... Semi-smart-ass answer: Not that secret if everyone knows about them, huh?

The National Clandestine Service (USA) https://www.cia.gov/offices-of-cia/clandestine-service/index.html #3. Australian Secret Intelligence Service http://www.asis.gov.au/overview.html #2.

Sure, they have a pretty good track record, and they don't do a half bad job most of the time, but it's hard to compete with such hard-hitting opponents as the American CIA and Britain's MI6 not to mention Mossad in Israel and the famed Direction Générale de la Sécurité Extérieure in France. CSIS is simply outclassed, but strangely enough, the Canadian government remains largely unaffected by the relative mediocrity of its foremost intelligence service. Of course, the best secret intelligence services are always the ones that no one knows about. The most effective are those that people believe cannot possibly exist. This is what makes Section 42 the most advanced intelligence agency on the planet. Who would believe that a bunch of backward Canucks could be responsible for the most sophisticated agency in the world? This, of course, is what makes the famed Section 42 so distinguished from its competition."

At this stage they just cannot bring ISI under fire directly so in the first phase they are blaming the retired officials and in the next phase they will declare the whole organisation rogue.” " Source and further information: 4) Further information: - "World Intelligence and Security Agencies": http://www.fas.org/irp/world/index.html - "List of intelligence agencies": http://en.wikipedia.org/wiki/List_of_intelligence_agencies

I think KGB and Mossad is at number 1 and 2. But i should accept that ISI is the only one who is fighting alone with almost 6 agencies. With very limited resources and technologies i will say ISI is at number 3.

The Mossad hands down! I put the rest... 2.SIS 3. CIA 4.KGB 5. Delta Force (had to throw them in there!)

Whether ot not the Mossad, KGB, SIS or even the CIA and NSA have all been labeled controversial, they all get the job done. Most of what they do is just and right.

You need stop to being spy, Boris. Finally, we catch moose and squirrel!

ISI should stand on no one posotion bcz she is fighting 6 other agances on Afghan border and touch to success in sawat a lot of RAW,s and Mossad,s and CIA,s agents easily killed by ISI members.before inter into sawat and malakand mossad,s CIA,S and raw,s agents are having bear when ISI and Pak army took action against this people there was no way run away for him fron sawat and malakand so thy cut thier bear and try to run but have killed some succeed to run..
