That is what Obama has done his entire career. He has worked to weaken and destroy America. He has worked to help the terrorists.
You can start with his partnership with Bill Ayers. Look at his alliance with Rev. ("It's not God bless America, it's God damn America. God damn America") Wright. You can look at his working with Louis Farrakhan and the nation of Islam. Look at his bowing before the Saudis who finance and support terrorists. Look at his support for rules of engagement that got American servicemen killed. Look at him freeing terrorists who have killed Americans and vow to kill more. Look at his support of the Muslim Brotherhood. Look at his funding of the so called "moderates" who ended up being the leaders of ISIS.
It could not be more obvious.
“Look at his bowing before the Saudis who finance and support terrorists.”
You’re halfway there.
“Saudi” Arabia and Pakistan are at war with us. They love it when we call their soldiers “terrorists”, because it blinds us to the nature of what we are dealing with.
