Ayers and North Vietnam

More information is arising concerning William Ayers and North Vietnam, and Ayers' wife Bernadine Dohrn's contacts with Fidel Castro.

The American Thinker has the story:

After returning from Cuba, Dohrn and others met with North Vietnamese and Viet Cong representatives in Budapest, Hungary, to discuss antiwar strategy on US campuses. Speaking a few days later at an assembly of revolutionary student movements at Columbia University, Dohrn reported that the Vietnamese communists she met in Budapest were working with US GIs in Saigon, attempting to obtain military information.
As a gesture of solidarity, the Vietnamese who Dohrn met in Budapest presented her with a ring made from an American aircraft shot down over North Vietnam. Bill Ayers would receive a similar ring while meeting with Vietnamese communists in Toronto. He later recalled being so moved by the gesture that he "left the room to cry." He said, "I realized...America was an evil... and that I was... living inside the belly of the beast...."

Now, Obama may not be best buddies with Ayers and Dohrn, but why would he launch his political career from their home, sit on a board with Ayers, and accept contributions to his political campaigns from such people? That seriously calls into question his judgment.
