"Fairness standards" (https://www.democraticunderground.com/1134143751).
It appears that no source which printed this severely abridged version of the story has any.
For the sake of fairness, and with fading hopes of the news media to regain theirs, here is the rest of what Matthew Miller said immediately following the cited comments:
At the 20:40 mark -
But here let me qualify that: there are to ways to think about the commission of war crimes - one is the state had pursued the policy to deliberately committing the war crimes or is acting reckless in a way that aids and abets war crimes. And that I think is an open question. I think what is hard... is certainly not an open question is that there had been individual incidents that have been war crimes where members of Israeli military committed war crimes. So ultimately, in every major conflict, including conflicts prosecuted by democracies, you see individual member of he military... the militaries... commit war crimes. And the way you judge a democracy is whether they hold those people accountable, but Israel hasn't been... that's my point, we have not yet seen them hold sufficient numbers of the military accountable, and I think it's an open question whether they are going to.
And earlier in the podcast:
Ar the 12:35 mark -
What I never heard from people who were criticizing us is what other policy they would pursue other than just stopping support for Israel which, yes might have hampered Israel's war effort - not over the short term - they had a lot of capability to continue prosecution the war but at least in my judgement - I know in President Biden's judgement - the judgement of other senior officials - would have left Hamas in charge and would have left us with unstable security situation that would have endangered the lives of Israelis and Palestinians for months, years and decades to come.
