We are talking about US politics here, so I’m assuming the focus is what the US has been doing.
Stop funding and supplying arms to Israel.
Like the $20 billion we approved earlier this month (in direct violation of the foreign assistance act)
recognize Palestine as a state
We simply do not do this. Then again we don’t recognize Taiwan either.
Back ICJ arrest ruling for Netenyahu
The US has been opposed to this warrent, and there is talk of sanctioning the ICJ over it.
Should anyone ever arrest any Israeli official pursuant to an ICJ ruling, there is standing US law (American Service-Members’ Protection Act, otherwise known as the invade the Hague act) authorizing the President to use full military force to secure their release [0]
Urge the UN to sanction Israel
The US is routinely the sole veto on every major UN vote on Israel.
[0] This isn’t Israel specific. It us authorized for bassically any ally that is not an ICJ member.
