I'm not sure how my idea will come across but here goes.
This Gaza conflict is complicated as F. I think most people agree with that.
Pretty much everyone that's touched it has blood on their hands by this point. And everyone in the fallout has been hurt in some immeasurably painful way.
The US involvement multiples the complexity because there is evidently a proxy between Hamas and Iran, and the US is already in opposition to Iran in other ways.
The US is also in the position of throwing its weight around in many other conflicts at the moment.
Diplomatically, this US is walking a thin line all over the place between needing to show strength vs compassion. Using negotiating finesse vs being strong fisted.
Inside the US, our representatives ideally can think for themselves, but as a party they hopefully work as a team to represent the American best interests, vis a vis "the people." Specifically, I mean the people don't always know what they want or how to get there, nor do they educate themselves as a whole about every issue at play. Not to mention that international diplomacy issues are very often not shared with the public.
So, yes, the average human with a functioning soul wants to see a ceasefire yesterday. But what if there is something else at play that we don't know about, which justifies not pressuring Israel to stop?
