Barak would be one of the most Liberal minds on concessions for the peace process. Even he has stated the corridor between the West Bank and Gaza will be a tunnel, that Israel will build on, Israeli territory and allow the PA to use and run it. Israel cannot allow a Palestinian state to have territory to cut the through and split the south from the rest of Israel. If you are prepared to make those concessions on Jerusalem, then why not sign a 25 year transfer of sovereignty contract in relation to East Jerusalem on the condition there is no terror conduct from the West Bank or Gaza, against Israel. Otherwise the contract has 2 years add for each attack.
