Jeff Bezos undoubtedly had nothing to do with this op-ed. He's a busy guy with Amazon, and has made it clear that he will stay out of the editorial decision-making at the post.
In addition, the authors of this piece are not folks who Bezos could push around even if he wanted to. The only way they would write this piece is because they wanted to.
Politically, this piece is a big deal. These are "national security establishment" type folks, directly disagreeing with their successors in government today.
I agree with your assessment that this piece is a big deal, politically.
I disagree with your "undoubtedly". I think there's a fair to middling chance Bezos did some meddling in the editorial process - made a few phone calls, dropped some hints, bent the ears of an editor or two. Newspapers always protest that financial interests don't interfere with their reporting, but time and again, we find out otherwise.
