Keo10, did you actually go to that site, watch the video (off YouTube last February), and take a quick look a the other very-rightwing fear-mongering posted on that talk radio site?
I'm no big fan of Barak Obama (I will be writing-in Ron Paul for President in November), but stating that Obama plans to "unilaterally disarm" America, based on that video clip, is more than a ginormous stretch. Actually, it is completely irresponsible. He was explaining that he would actively discuss arms reduction measures with other countries, with the intent to act on those discussions.
This was the first that I've ever heard of any of this. Since it's four months old, and the MSM has seen fit to ignore it, I would give it zero weight.
There are thousands of overactive pundits on both the far right and far left.
