Every time I encounter the "don't vote" brigade, my first thought is that it's a Russian or Chinese troll trying to get Trump elected again.

My second thought, which is a bit more nuanced, is some introspection on what Biden is actually doing. He has three options with regards to Israel, none of them good.

1. He could deny them weapons, which would inevitably lead to outright war with Iran and an increase in Russian influence in the region, as well as a loss of an ally.
2. He could fully commit to Netanyahu's madness (i.e., what Trump wants to do), fully empowering genocide while using no political leverage on Israel. This would also ultimately lead to broad regional warfare, which will also likely increase Russian influence in the region.
3. He could try to limit the damage by imposing conditions on weapons sales and attempt to thread the needle, recognizing Hamas for the grotesque terrorist organization it is while using political pressure to prevent as much needless death of civilians as possible. This is what Biden is trying to do.

I don't know that Biden is doing a very good job with #3, but #1 would be a catastrophe, and #2 is what Trump wants.

This is a shitty situation in every conceivable way. Our ally, Israel, is currently being run by a corrupt and genocidal freak. There are no good answers to a situation like that beyond Israel coming to its senses and throwing Netanyahu in prison. But there are plenty of really bad answers, and Trump would be the worst.
