You're still falling for the cover story that they'll settle for 67 borders.
They've made it clear that they intend to continue the conflict after getting a "peace" deal. 3 and 4 will give them more military ability, thus more deaths.
Palestinians
may not settle for 67 borders in some hypothetical future scenario. But Israel is not settling to 1967 borders
now, and is continuing the conflict as we speak so that's a moot point. The current conflict is already taking thousands of lives each year. The Palestinians would have to be several orders of magnitude better at killing Israelis if they wanted to beat that, which you could argue they
want to do, but they would need a thousand times more rockets, a thousand times more funding, and a thousand times more people. It's simply not a realistic scenario.
