Firstly, I doubt PCPSR to be a reliable ...
Usual conspiracy theorist; deny any source you don't like. But it's not surprising that you are so quick to deny the voices of Palestinians as collected by a Palestinian polling agency.
I would do 2 things:
1. I would immediately end the war and instead go after Hamas leaders in targeted assassinations and air strikes.
2. I would evacuate the West Bank, and go back to the 1967 borders. I would also lift all blockades, release all illegally detained Palestinian prisoners and work to establish a sovereign state of Palestine. Of course this has to be done in stages, and I would atleast take the steps to reach that state and put forth a roadmap to realizing that end goal. And before you say Hamas or anyone else will not agree - they will. Infact, that is Hamas' demand as well, to go back to the 1967 borders - per their charter. There is no existential threat to Israel.
1. And how would you target Hamas leadership? Would you send troops into Gaza to do this? Bomb their homes? Sounds pretty much like what Israel is doing. And what was your response to Israel hitting Hamas leaders in lebanon?
2. Hamas has said they would accept a Two State peace as a TEMPORARY measure. They and 75% of Palestinians are clear that their end goal is to have a Palestinian state "from the river to the sea".
And it would be stupid for Israel to give up land without any guarantees. That's why I have always said international pressure to negotiate is the only way forward.
p.s. Olmert offered all that in 2008; a Palestinian state on all of West Bank and Gaza with 6% land swaps including a land corridor to Gaza, international oversite over the Old City and holy sites, some refugees to Israel with the rest given money to resettle in a Palestinian state, the countries they live in, or third parties like Canada (and only 10% of refuges want to live in Israel). He even offered to remove Jews from Arab neighbourhoods in East Jerusalem. Abbas walked away without even a counter-proposal and Hamas rejected the concept out of hand.
