secret service

(Secret) service
The previous week an article that claimed that the French secret service, D.G.S.E., had warned CIA about a possible attack from terrorists during the first months of 2001, before the attack that took place on 9/11/2001. In the same document from D.G.S.E. mentioned, also, that Greece or Cuprys may be target for a terrorist’s attack and thus D.G.S.E. reported that to CIA instead of the greek secret service!
From these and many other examples it is obvious that CIA has much more power than any other secret service in the world. It has the power to control even the regime of a foreign country. For instance, in Greece on 21 April 1967 some militarymen made a coup d’ etat and CIA not only knew about it but it supported it and this is a fact, not an opinion. The question is how much power does CIA really has and who controls CIA?
In my opinion we are never going to learn the truth about what has CIA actually done, because I believe that what we learn is a tiny percent of what it really does. I can’t tell if they give on purpose some of their actions and reports to the media or not, but I know that they know a lot more than we imagine.
Another thing that is odd, is how do they gain access to all these information. It is logical to have many agents around the world, but this cannot explain the number of confidential information they defalcate!
I expect that many hold that common people shouldn’t know much about secret services, because then they won’t be secret! I understand and share this opinion, however I believe firmly that someone should control the secret services and who can judge better than the common people? Therefore the common people shoud know more about the secret services generally (not, of cource, about their current actions or the agents)
