tangentially is that places like Lawrence Livermore Labs use 'super computing' to evaluate the designs of nuclear weapons, thus (hopefully) obviating the need for actual testing....In regards to the issue of "Open Skies" I've also heard that the role of 'over-flights' involved more that looking for evidence of Nuke tests...they were also tasked with finding evidence of major troop movements that could logically be considered as "pre-war" provocations...it's this aspect (if true) that has me worried...especially given Vladimir Putin's propensity for not practicing "Good Neighborliness".
I also don't know how, or if, "Open Skies" and satellite surveillance work together...perhaps "OS" is superfluous and too costly, like the SR-71...just some hairs going up on my neck, and would like to hear from truly knowledgable military and IC folks...Chris seems to be plugged in to some degree.
