Frank isn't that deep; he just wants to fit everything into his worldview that Israel is evil incarnate.
It doesn't matter how he got there.
Even if I accept your description, he still ended up in the same place to make it work.
Trump is out there saying Israel needs to be stronger and that they need to "finish the job" but he's still going to insist Trump probably would be better than Biden.
I haven't caught up, but I am sure that any of the recent announcements about humanitarian aid are just more proof Biden is pro-genocide.
Anything that lets people think something is being done is bad because it means people have cover to do more genocide.
I think I've seen the argument on twitter that the proposed dock is actually a way for the US to invade Gaza directly and commit the genocide themselves.
It's all about working backwards to the pre-chosen conclusion at this point.
