This is the breakdown for US nuclear security scorecard, an area of interest being considered here is "Insider Threat Prevention".
Considering the recent personnel infractions who were in charge of US nuclear arsenal, what seems interesting is that all of areas related to that in the scorecard is 3 (which I assume is highest trustworthiness factor for vetting personnel).
If someone can explain how this is calculated and clarify the whole scoring process, it would be great.
While accountability and detailed analysis may be useful to examine pain points due to such reports, to think that such reports are the gospel of nuclear security is incorrect.
Many nations who supposedly are superior in "nuclear practices" did invade countries where no WMDs were found, tried to block nuclear programs of developing nations (CTBT anyone?) and so on.
So to assume that certain countries when score poorly means they really suck is plain wrong considering the credibility of nations who back such reports .
