Pressure and sanctions on Qatar and Iran to withhold funding.
Pressure on everyone to stop aid funding, knowing it was being diverted for terror.
Support (even material support) for Israel's naval blockade.
Monitoring of the Egypt border (for real, not UNFIL style).
Require fair and even monitoring by actually neutral NGOs.
Proper supervision (or better yet, dismantlement) of UNWRA.
Insist that no negotiations are to occur until hostages are released.
Demand the end of pay-for-slay.
Make economic support of Palestine dependent on peace treaties and agreements.
Stop using loaded and libelous language.
End lawfare.
Make the silly UNGA resolutions and non-binding UNSC resolutions against the government of Gaza.
How's that for a start?
