Does "her own" include the trillions we have spent on the them?
do you understand what Israel would (not could ) do if the US did not retain some influence.
Drop the aid and
1) You will screw your political support in the US
2) The opposition to Israel will get bold enough to think that Israel is weakened
3) Israel will no longer pay attention to the UN/US requested for restraint.
4) You will see the same results in Gaza when as what happened in Lebanon. Hamas will get rolled up into the Egyptian border. Then Egypt can decide to open the floodgates and let Hamas escape or the Hamas military wing will go down in flames. In the process; Gaza will get flattened. The the Palestinian lovers can provide supplies to Gaza that has had their urban area demolished.
LL, SE and other Palestinian supporters may claim differently; that the world will intervene. That will not happen until Hamas in Gaza does not exist. It wil also send a nasty message to Abbas and the West Bank.
