i'm not hostile to the overall thesis but

These administrators—the ones who make up most of the foreign policy bureaucracy that the Obama administration derided as “the Blob”—are the ones angriest about American policy in Gaza.

ooooh i wouldn't say that around a palestinian lol

Within context, this sounds like they're talking specifically about those inside the Executive branch of the United States:

But the further down the ranks you go, the more pervasive the anger at the US’s complicity in mass slaughter becomes. An entire contingent of junior White House staffers, for instance, made up a “staffer bloc” in pro-ceasefire demonstrations in Washington, DC. As a former US diplomat, I know that many people have resigned quietly and anonymously over Gaza. Many want to quit but literally don’t know what other work they’d be qualified for. These administrators—the ones who make up most of the foreign policy bureaucracy that the Obama administration derided as “the Blob”—are the ones angriest about American policy in Gaza. They are also the ones who can do the least about it, and they know it.

(That said, I have only read part of this article so far)
