You provided a false dichotomy, I don't have to choose: https://en.wikipedia.org/wiki/False_dilemma
> Exactly so to resolve the current situation, Israel has no options.
I support removing Hamas but not cutting off aid, electricity, fuel, food and not indiscriminate bombing. And I think pairing that with a robust drive to a 2-state solution is also key. You have to provide hope and show you are not just trying to take land or engage in ethnic cleansing, e.g: https://www.cbc.ca/news/world/israel-gaza-palestinians-conce...
> Doubtful that the court would convict Hamas anyway for just killing a few jews.
I would expect that some of both Hamas and Israeli leadership will be charged and also some will be found guilty of war crimes if ICC filed charges. ICC has been gun shy to get involved though, so it isn't clear if it will happen.
> Any long term solutions can come later.
Always! This is why the occupation has lasted so long.
> Also assume the US should just bring a UN court case against the Houthis in Yemen as well instead of using force to defend ships?
Israel isn't charged at the ICJ for self-defence. It is charged with genocide with is different and not what the US is doing in Yemen. Many leaders said things that sound like genocidal statements and it has cut off food, water, electricity and fuel. 80% of starving people in the world are in Gaza.
