OK, since you cannot manage to screw up the courage to go there, I'll bring it to you. Here is a significant part of the article. It shows Mattis bracketing the issues generally enough, but then creating a more specific context by aiming them squarely at the extremely unlikely scenario of "an ambitious leader, unfettered by conscience, or precedent or decency, who would make himself supreme."
Regarding failures, Mattis rightly says "we" but fails to cite the main instigators or the more present danger of "an ambitious ['swamp'], unfettered by conscience, or precedent or decency, [which] would make [it]self supreme." The Dems are an especially real problem in just this way, and do not show themselves even close to being trustworthy. Despite your claim to the contrary, the article does not have Mattis greatly explaining the situation, though it would be great if the Dems took that closing invitation to heart.
I literally quoted the part of the article that helped make my point. For whatever reason you are quoting everything but that in this response. Are you being deliberately obtuse?
So you accuse me of making a point that isn’t there and then rail against Democrats which definitely isn’t there either.
