Oooft. Dark, but accurate.
Cue the usual suspects coming along with "but Hamas/Hezbollah commit atrocities too!"
We know. And nobody is happy about that either.
My mind was wondering last night and got to the conflict. Obviously hypothetical, but if everyone backing the various sides was to pull out and let them crack on, where would things end up? I reckon it'd be a Troy style siege scenario, with Israel battening down the hatches and hoping whatever munitions they had left would see them out before their opponents got bored and started on each other.
Either that or they go gung-ho with said munitions and try to wipe everyone out, but I don't think that would end well for them.
I think it depends just exactly what you mean by "backing the various sides".
If "the West" stopped backing/supplying weapons/intelligence/etc to Israel, and, who ever is "backing" Hamas/Hezbollah/Houthies/etc stopped their backing in similar way, my gut feeling is that it would degenerate into an ongoing conflict with the Israelis "winning" initially, but, eventually, Israel and neighbouring countries would just become a hellhole collection of failed states.
But, we all know that is not going to happen, too many vested interests for the "backers" to stop feeding the monster.
Ultimately, there will have to be some form of Political Settlement, or, alternatively, sooner or later, some miss-calculation will occur and there will be a nuclear exchange, or, a release of deadly toxin. My money is on the latter (sadly).
