Sherlock Holmes and the Settlements

Sherlock Holmes, if he were negotiating the settlement issue, would look at every possibility, eliminate those that don't work, and the one left standing would be the solution. So, let's look at the possiblities.
1. Follow the example of Gaza and remove every settlement from (soon to be negotiated) Palestinian territory.
2. Allow all the settlements to remain, and those that are within Palestinian territory would have Jewish residents of Palestine. This is assuming that the land is more important than the government.
3. Keep the major settlement blocs and compensate the Palestinians with an equal amount of land from Israel.
4. Drive all the Palestinians from the West Bank into Gaza, Jordan, Lebanon, and Syria, and make the entire West Bank part of Israel.
5. Continue the status quo.
What would Holmes do?
1. Settlers from Gaza still have not all been relocated in Israel, and their numbers were much smaller than the population of the West Bank. Logistically, bringing all of them back into Israel (even if it was a peaceful evacuation) does not seem possible. And that is not even taking into account the ideology of the settler movement.
2. I don't think Holmes would have a problem with this solution. There are those who consider the government of Israel to be illegitimate, since it wasn't founded by the Messiah. The commandment is to live on the land of Israel. The West Bank is still the land of Israel, though under this plan, governed by another power. In time, with the coming of the Messiah, it would return to Jewish hands.
3. Holmes would also agree to this plan. It seems to make the most sense. For it to work, the Palestinians would have to agree that settlements are a matter for negotiation, like borders, refugees, water, and Jerusalem, and not make them a pre-condition for negotiations.
4. Out of the question. Israel would become even more isolated than it is, and would exist in a continual state of attack.
5. More Israelis would become disillusioned and leave. Emigration is already an issue for Israel. With no hope in sight, and with the religious right gaining more power, secular Israelis would leave, creating a brain drain. Israel would continue to be isolated, and ultimately, the liberal to moderate American Jewish community would have trouble unconditionally supporting Israel.
So, I think Sherlock Holmes would conclude that the settlements become part of Palestine if Jews are willing to live under a Palestinian regime, or concessions must be made by both parties. His ultimate conclusion--only the Messiah will clean up this mess.
