There are a lot of conspiracy theories about the assassination of President Kennedy, and it seems to me that's for sure only that we will never know the full truth.
President Kennedy was indeed a charismatic leader who started a real change in America by supporting the movement for civil liberties in America, the unification of Berlin and Germany and the beginning of the US space program.
I think that Russians are responsible for his murder, he was their most dangerous rival, and even his killer was educated in Russia.
I agree with zou. It is truth. Kenedy was very a charismatic leader who want to improve acquaintances on the world. His policies was sent a lot of criticism. I also think, Russia is responsible for his murder. Simply, fight for predominance on the world.
