Sharon's vision is totally incompatible with either Bush's Road Map or, more importantly, with a final settlement to the Palestinian problem. No real solution will take place until Israel recognizes a viable Palestinian state occupying Gaza, most of the West Bank and East Jerusalem. This doesn't mean that all settlements need be abandoned (even the Palestinians recognize that reality), but it certainly does not allow for sharon's "tunnels and overpasses, and the like."
