I think the limited actions in Iran are not at all comparable to the commitment and risks involved in directly defending Taiwan from invasion or naval / aerial blockade. With that said, I do think that the US is likely to intervene in some capacity regardless of admin, but slightly less so with the current admin.
I am pretty sure the US is investing hard into naval drones. There's a reason Russia cannot use it's naval fleet in Ukraine as cheap torpedos and drones destroy ships.
Ships are basically sitting ducks if they are within range of drones. I am surprised better anti drone weaponry hasn’t been deployed. I would think bird shot cannons would be highly effective.
