<<Fact remains the editorial was based on supposition of future events, and unless the WaPo editorial board is clairvoyant, that hardly counts as more than conjecture. >>
BT, the editorial was based on the "President's" reservation of powers to do certain things which the paper objected to. They don't object to the reservation of the powers because they know that they won't be used. They assume that the "President" reserved the powers because he intends to use them. It seems common sense that if he has no intention of using the powers, he would not be wasting political capital in retaining them.
If a bill were passed giving arbitrary power to the Chief of the General Staff to arbitrarily suspend any newspaper in the country in any national emergency, would you object to an editorial opposing the law on the grounds tht it was mere conjecture?
It seems to me that there are many editorials based on supposition of future events like Iraq misusing WMD or Iran developing nuclear weapons, and I don't recall you ever using terms like "clairvoyant" or "conjecture" with regard to them.
