"Unless there is a two state solution, there is no defensible solution, and flattening Gaza doesn’t change that, it just creates more terrorists, more instability and more hate."

I agree that all outside observers agree that a two state solution is the ONLY way forward.
However both Israel and Hamas (and Hezbollah and Iran) reject this.
I would also add the removal of West Bank settlements (200k people which is not going to be easy) and the Gulf States making sure that the West Bank is an economic success.
But even if Israel agreed to a two state solution then Hamas are still committed to the destruction of Israel and further attacks on Israel . So that leaves the only options left as the removal of Hamas or the removal of the State of Israel. Which is why Israel is so committed to the removal of Hamas because it still wishes to exist- giving us the current conflict.
But as you correctly point out even if Israel managed to "defeat " Hamas then the destruction of Gaza and deaths of Gazans will simply create more hate and desire for revenge creating a Hamas 2.0 (which already exists in the form of PIJ).
Which is why I sadly see one of outcomes being "last man standing ".
Alternative ideas could be giving Gaza to say Egypt except it really doesn't want it or it being militarily occupied by another country say Turkey - all of which are fraught with difficulties and which I can't see working.
