I did not watch all of that.
All countries need a Secret service for overseas intel full stop.
What I can tell you is that the CIA has a terrible reputation both for endangering allies and getting it all wrong.
When the South Africans were in Southern Angola in the 1980s the CIA went in nearly got my Captain who was escorting them killed.
They listen to no one, put others in harms way with out a second thought and when the shit gets real they run away (they stayed too long against advice and then grabbed the plane used to bring them in leaving the South Africans stuck in a war zone)
It was actually a standing joke that the CIA has standard procedures in place for deserting allies
