I think if they were involved it will backfire on them. The reality is it is now going to be a lot easier, and the military-industrial complex is extremely eager, to put aid for Israel as a joint package in aid with Ukraine. Net result may be that aid is enhanced for both nations.
Edit: that said they do want Iranian drones. I could see them supporting it from that perspective and also happy to run their misinformation campaigns for them to dry and drive a wedge.
