Here is a question that has plagued humanity for years, and we are going to answer in here at PF. What is the best intelligence agency in the world? First, a few caveats: -I only listed a single intelligence agency from each country. -The selection was based on what agency is currently and primarily responsible for collecting external intelligence. -If your choice is a historical intelligence agency (eg. OSS-U.S.), or simply not on the list (eg. Quds Force Intelligence-Iran)plus tell us what it is, why it's your choice, and what country it works for. Prior to considering which intelligence agency is the best I recommend thinking about their ability to carry out operations, analyze the information they have, and the price for their intelligence failures. My choice is the CIA. I would've selected the Mossad because their stories slugging it out with Black September, and acquiring the Mig-21 put James Bond to shame. But their price for failing to predict the Yom Kippur War, the Lillehammer incident, and the failure to accurately assess the threat posed by Hezbollah in 2006 were grave mistakes. In fact, the Yom Kippur war almost pushed the IDF to the breaking point. PF, tell me, what is the best intelligence agency in the world?
