Is government all about lies and control?

I am reading Tim Weiner's 'Legacy of Ashes: History of the CIA' which depicts the CIA and the US government as built on layer upon layer of lies and intrigue all with the aim of controlling the world, or rather running the world via proxies, stooges of the worst kind..
The book gives some nasty revelations about JFK's death: Could he have been killed by a guy sent by Fidel Castro? (One of the agency's bosses seems to have warned the leadership that once the agency eliminates other countries' heads of states, there is no stopping such countries from coming for the head of the US president and/or leaders). I begin to understand the US-Cuba frosty relationship; and that of US-Iran.
interesting read. Now, if only someone could do an exhaustive writing o the Kenyatta and Moi governments then another does the Kibaki government (that will have to come like in 30 years time, I guess)... that would make for great reading.
