It seems to me that this is the one political position the author has: "America bad." And everything follows from there. Russia invades Ukraine: Actually it's America's fault, because NATO expansion is violating non-existent treaties. Israel bombs Gaza and does the crimes against humanities: Actually it's America's fault, because Israel is just imitating America.
This seems like the usual "what aboutism" from Russian or Chinese propaganda.
What Israel did is really really bad, but America didn't force them to do it. And America's response of unconditional support is also bad, but they generally didn't want this conflict, because it's not useful to their agenda.
America does enough bad stuff, no need to invent more.
To be fair, and I hate to play Devil's advocate to this bullshit, but the US tried to share their "lessons learned" with Israel. The US repeatedly told Israel to not go full in like the US had done in Iraq and Afghanistan (read Felluja). After Fallujah, the US changed tactics and took a more "small strikeforce", infiltrate and assassinate approach. Israel basically told the US to shut the fuck up and just started blasting.
There's nobody better in the world to tell you how to avoid war crimes than someone with decades of experience in committing war crimes.
