None of these are mistakes by Obama. They are intentional. His goal and aim is to decrease American prestige and influence overseas. To destroy a system that he sees as harmful to the world. It’s exactly WHY they ignored the warnings of the attack. He knew the result...the weakening of the United States.
Put simply, Obama wants to fundamentally transform (remember he said it multiple times) from a capitalist system with global reach and global influence to something else. To get to that something else the United States must become in essence a 3rd world country. It’s his vision of a utopia free from the evil influence of our “financial overlords.”
Bumpity, Bumpity, Bouncing Betty Bump!
Summed up nicely in “2016.”
