MI6 is quite a nasty secret agency. Behind all the nice hollywood-clichés, they are a very nasty organization that has a list of horrors on its name:
- albanians uprisings of the 50s
- OUN/UPA funding of the 50s
- iranian coup of 53
- guiana coup of 64
- working with the cia to arm mujahideen in the 80s
- lybian terror operations of the 00s to get back oil
- disinformation operations for iraq wars(operation mass appeal) in the 00s, and many others
- assassinations(for example in kenya even recently)
- work with nazi collaborators in many eastern countries in the past 30 years to destabilize governments
- trapping julian assange
- implication in bombing operations all across the world(for example operation goldfish)
Remember they are allowed to operate in a completly unrestricted way even against british citizens. They are as bad people as Mossad and CIA.
