Wow - what a big news story. A number of miltary men advise that in a nuclear world, the major alliance cannot dismiss the idea of first use of nuclear weapons. They have only re-stated what has been the policy for 40+ years.
The Guardian dressing it up as a knew dangerous threat to world peace. It panders nicely to their readership who will now fret about those nasty violent men in charge of armies. They might as well have included a link to the CND membership renewal page.
