This way, the Houthis are to blame for the Palestinian lack of aid and now become part of the guilty of genocide. If Israel does not remove forces then we stop all military support for Israel and put sanctions on their supplies. If Hamas refuses to let hostages go, then aid should stop to the Palestinians and the blame is put on them for lack of supplies. It is about give and take. Doesn't have to be exactly this way but the principle must hold. Something for something and nothing for nothing.
