It’s not realistic.
The US stays in for geo-political reasons, but let’s say the US and all other countries stay out of it.
There would likely be more death. I guess we could be optimistic and hope without all of the money and arms coming in Israelis and Palestinians might make peace, but that’s doubtful.
So, ok, fight to the death. That means cutting off the food aid coming into Gaza too. I think Israel is probably more self sufficient than Gaza and West Bank, more trained, and then if they conquer those areas then what? The Palestinians who survive finally stop any aggressions once and for all? Doubtful.
If the Palestinians win, then they have rubble left, snd start from scratch, because I feel pretty sure if the Israelis surrendered, on their way out they would blow up Israel’s infrastructure in their wake, which they did not do when they left Gaza in 2005, but giving up Israel altogether that they built from nothing, I don’t see them handing it over easily.
Sounds horrible and probably wouldn’t completely fix the problem, because some extremists will likely still be around.
I can’t tell you how badly I want the war to stop and the Palestinians to be safe and for Hamas to be disabled. I have a fantasy that once Hamas is crippled there will finally be a peace treaty and life gets much better for everyone there.
