Here's a hint: MOST nation's Intelligence Budgets aren't PUBLIC. Secondly, a LOT of our intel goes into what is euphemistically referred to as "national technical means". Meaning Spy Satellites, which aren't cheap, even as satellites go. 1 Estimates for a 1980's spy sat in current dollars is 2-3 billion EACH. Now, I don't know how many current spy sats we have, but I'm going to guess at LEAST 10, and we seem to launch several every year, so call that 10 billion.
Then you add in ground infrastructure, which, from my experience, equals that of the bird in cost (I've worked in Aerospace, and seen budgets for Commercial sat programs, and the rule of thumb holds there. Add Government costs and Classified, it's probably more than that. . . ). So my guess ? At least half, if not more, is "national technical means". And that includes ALL the lovely programs that Snowden kindly let us all in on. . . I don't know if you've seen the parking lots at NSA and CIA. . .but there are obviously huge amounts of people working there from the overhead view, , ,
As for Newsweek, well, they're media. And lately, unless there's a scandal, all the coverage makes .gov types look like a cross between the Buddha, Jesus, and Superman. . .
