Fake News? CNN Claims Iran Tried To Seize UK Tanker

Ron Paul: Yesterday CNN was the sole source of an article accusing Iran's Revolutionary Guard of trying to seize a UK tanker in the Persian Gulf. Though CNN claimed there was video of the attempt, none has surfaced. Iran strongly denies any such attempt. Is this another psy-op to drum up support for a US attack on Iran?
Bonus topic: A new Pew Poll shows that US military members do not believe recent wars have been "worth it." Maybe we should listen to them.
