> 7 trillion in military spending is unaccounted for

If someone gave me $100, and I handled it without keeping track, that's $100 not accounted for. But we do know that I was given $100, and the money went somewhere we just don't know where. But it doesn't necessarily mean that this was shadow money outside of the larger picture budgets, people still know I was given $100. Its not like now there's somehow $200 spent because I was given $100 and I failed to account for $100.

So thinking about the $800B defense budget, if they fail to properly track $150B of that budget, that's another $150B added to that pile of unaccounted for money. But its not an extra $150B that got spent, its still a part of that $800B.
