The land belongs to Israel, legally.
There is no such nation as Palestine, that is a lie.
There are no such people as Palestinians, that is a lie.
Some of them came from this land when Israel was established (again, legally). They left voluntarily, because they believed that Israel was going to kill them. (They believed this because they have been killing Jews since the days of David.)
In fact, those Arabs that never left their houses, still live peaceably in Israel and have better rights than in ANY Arab land.
The claims they make are only to fool uninformed people.
These people have been offered their own nation, twice.
They have REFUSED.
They plan to take over Israel and kill every Jew in it. They say so, often.
They need YOU, however, to help them.
