Senator Roberts said; " You can not go one on one in negotiations with North Korea, all they do is resort to rhetoric"! In response to other questions by Brit in regard to Iraq, the articulate steely eyed senator quaffed but added that he knew what Brit was inferring. This indicated that he could readily read between the lines of the question but choose not to offer a clear answer because of security concerns.
Then as the questioning by Brit continued; "Just how serious are the Republican Senators in keeping the Senate in extended session in order to force a hard filibuster"? The good Senator, chest out and bristling, resorted to classical North Korean rhetoric to avoid a straight-forward answer. Brit continued by asking the same question in four attempts at a clear answer. The good Senator obviously ( I say obviously rather then CLEARLY) had an agenda that did not include answering the question that was being asked.
In a past candid interview long ago, Tony Snow had explained the scenario of the questioner and the questioned. The show's host would not press for a straight answer beyond three or four attempts if the politico being questioned clearly didn't want to answer. You know, like a gentlemen's agreement.
