Well few reasons why I support one state:
There are two lakes in the map- big and small, and a river between- which is the border with Israel and Jordan.
Tel Aviv is in the shore. Jerusalem is in the mountains inside (you can see the green line which serround the "WB" that was released in 67.
Now there are many Arabs in those mountains. Why won't we get rid of that and live peacefuly in the green shore close to the sea? Well, apperently it is problematic. Those mountains are completely mingle geographicaly with the other parts- water, sewer, transportation- the "WB" is somewhere in the center of Israel. So despite the plenty of Arabs there, it is almost impossible just to slice it from the other lands around.
Strangely, settling increased Jewish birthrate. So i'm not sure we should obsessively focus at slicing areas with Arabs.
Historicaly Judea was in those mountins: Jerusalem, Hebron, BethLehem, the dead sea. It brings a spirit to our religious (who make children).
And the settling strength Jerusalem, which is inside those mountains and the capital of Israel and the reasons Jews are here. Without the WB Jerusalem will be isolated and serrounded, with one road to Tel Aviv in the shore. See, its problematic.
How the process of giving autonomy to the Arabs in those mountains in the center (West Bank) evolved: Israel brought dozens of thousands of terrorists organization (Arafat its leader) back to Israel (He was in Lebanon and Tunisia), and gave him control on the Arabs. This is the PLO, the Palestinian authority now. Quickly this organization incited the people, with Nazi education, and launched a harsh terror on Israel in few years (2000-2003). In 2003- Israel re occupied the Palestinian autonomy, but still they have internal independency. And Israel have serrounded it in wall or fences. In 2005 Israel evacuated Jews from Gaza, what created there a vaccum which was exploited by Islamists like ISIS, which ever since firing rockets indeed to Israel. Israel is suffocating Gaza, so things are under control- but for how long can it last- we all know it is not a solution, just a temporary bad tool. This Hamas in Gaza declares it will build an army to destroy Israel completely when having a free port.
The point I see is neglecting complete control over parts which are inside you, will leave them to international Islamists powers to interfere the Arabs, and soon to a total war or harsh terror. I will be the one to pay the resaults, not you. I don't want 48 again. People here say it is moral to let ultimate freedom, and than if there is a clash we will enter and have legetimacy to have a serious war if needed. I don't want that serious war nor I believe to the legetimacy crap. I saw in these 20 years of Palestinian autonomy experiement that they were not independed- instead of Israel, Saudia Qatar and Iran have entered and played local politics, and used the Paelstinians as tools to fight Israel.
Also, the two states process have led to half a million of Arabs to enter Israel. from Jordan. Thats demographicaly bad for me. in 2000-2003 10% of the Palestinians left to Jordan though. But still..
Anyway, I don't believe such a small land could split into several states, especialy in this harsh area. The Arabs are Arabs, and feel part of global Arab processes. Not all Arabs can be independed- I did capture a territory that could potentialy be an Arab territory, but instead its Jewish. And trying to limit me to the minimum, to one city, sin't ging to work. Israel is very small anyhow. Over time, Israel is shaping its form, and whats shaping it is stability, demography and wars or quiet. For instance Syria shoot over the north of Israel from the Golan heights daily. And since 1967 it seased. We have quiet. So thats a relatevely stability. Slowly we will see what is formed, but since 1948 didn't bring peace- its not the final borders.
Arabs in Israel have to be a minority. Independency they should seek somewhere else. As to the Arabs in the autonomy- it is a strange thing. But over time we will see what status will be. Again, like Gaza, this is not an ultimate status. They either be at war and expeled or annexed completely over time, or in this strange situation having autonomy regulated by Israel which is odd but for now I don't see a better option unless striving toward a clash.
