Thanks for the kind words. For the time being I will focus on Nixon and Obama because they are so similar.
I don't think Obama had any role with the CIA or 9/11. I am not aware of any such evidence.
Who is to blame for the Vietnam War dead? The American people.
So, the President of the US is not to blame for getting involved in the war? Then you shouldn't be blaming Obama for someone getting shot either.
Either stay consistent, or don't try.
Is it only Obama that is to be held accountable for actions in office, all other pres will be given a free ride?
