If the Arab nations surrounding Israel got weapons of mass destruction and nuclear capabilities,Israel would face extreme terrorism.

If this were to happen, Armageddon would surely occur in the Middle East and Israel.
The creation of a new Arab state, a Palestinian State, would seriously raise the risk of nuclear war.

If Israel has to face a new Palestinian State, it would be extremely unprotected from hostile neighbors.
It is important to understand the PLO's plan.

There are 4 cities in Israel that the Palestinian's want.
All that would be left of Israel would be a small section of land about 7 miles across.

This doesn't leave much room between this territory and the Mediterranean Sea.

It is the PLO's goal to drive Israel into the sea.

At any point, they could move a terrorist army across the West Bank and destroy Israel.
The Arab nations cover a hugh mass of land.

They have plenty of room to accept the Palestinian refugees into their own nations,why Israel?

They want to use the Palestinians for their political reason to destroy the nation of Israel and force the Palestinians/Arabs in to take over the Israeli land.
According to the Bible, Israel is the spiritual capitol of the world.

That is why all the nations are focused on it.

Israel is a little sliver of land surrounded by Arab nations.

It doesn't make sense for the Arab nations to be so concerned about such a little piece of land.
