That link is broken for me but I assume you meant to link to [0]. I think if there is a “safeguard” in a system, that definitely fits the bill of a supply chain risk. The only vague term here is “adversary”.
I don’t see a contradiction here. If control is out of the hands of decision makers, that’s a supply chain risk
. Were it not for that, the service is seen as critical to national security.
I dunno, safeguard seems like a weasel word here. It’s just reserving control to one party over another. It’s understandable why the DoD(W) wouldn’t like that.
