The de-facto starting point. (it illegal to gain land through war - Geneva conventions) Israel needs defensible borders but it cannot do so by annexing land. The final size of Israel and Palestine are to be the same as within 1967 borders. The territory exchanges have to be negotiated and agreed. The other side is if no other agreement can be negotiated, the border will be the 1967 borders. It is up to Israel to offer the Palestinians a border that they agree on. Otherwise, we move towards boycotts, etc to encourage Israel to come to the table. The Palestinians have already offered 1967 borders, what it Israel willing to offer. . .
