I might be horribly misreading this, but it reads like they're talking about no specific threat or problem but rather arguing if that was part of the contract or not?

If that's the case then shouldn't lawmakers, being lawmakers, pass laws so that future government projects include a clause in the contractual arrangement? Isn't that just common sense?

Seems like this is a trend with the US government, they try to find others to blame instead of just fixing the damn issue. They had this massive set of hearings about people abusing military disabilities (e.g. claiming for disabilities obtained before joining the US military) but didn't actually, you know, fix the freaking issue -- or even try to. They just berated the people being advantaged from it.
