Are the marks //\\ indicative of the "bridge is up" or the "bridge is open"?
I took the marks to signify a nuclear missile or weapon per the Clancy novel "Sum of all Fears."
The title is a reference to nuclear war and to the plot by the novel's antagonists to reconstruct a lost nuclear weapon. The title comes from a Winston Churchill quote serving as the first of the novel's two epigraphs:
"Why, you may take the most gallant sailor, the most intrepid airman or the most audacious soldier, put them at a table together—what do you get? The sum of their fears.
— Winston Churchill
