One problem is that certain countries in said World seem to have picked up the “giving material support to those committing genocide” option, which goes way beyond the more neutral “closing your eyes” option that would seem to be the safest one since - and I agree with you on this - there really are no good options at this point given what’s happenned so far - Israel has really been fucking up the Palestinians but forcing Israel to actually stop doing that and give back the Palestinian Land right now (which is probably not possible) would be rewarding Hamas for its choice of committing terrorist acts and would incentivised them and others to do more of it.
The second problem is that there are a lot of ways of going about the whole “fighting Hamas” thing and “the world” is not just letting Israel attempt to disloge Hamas but actually letting Israel do it in unnecessarilly bloody ways (the blockade of food and water being a prime example) - even genuine self-defense is not a valid justification for choosing to do it in the way that causes the most suffering to civilians.
Whilst I agree that there are no good choices, I believe the whole “unwavering support for Israel” choice which has tied certain nations to what is already a Genocide is almost certainly influencing the current Israeli government to feel that they have total impunity and will get away with killing tens or even hundreds of thousands of people for the purpose of triggering what they themselves describe as their objective - a “Second Nakba” - so the choices they are making are immensely worse than those they would be making if they feared repercursion from going too far (this is why I keep blaming western powers such as the US, the UK, France and Germany - the “unwavering” and uncritical nature of their support is what is enabling the Israli leadership to turn a “no good choices” situation into the far more extreme situation which is a Genocide).
